Charles Simmons appeals from a judgment of conviction, entered in the United States District Court for the Southern District of New York, before Judge Thomas P. Griesa, after appellant’s conditional guilty plea to the charge of possession of heroin with intent to distribute, 21 U.S.C. §§ 812, 841(a)(1), 841(b)(1)(A). In pleading guilty, Simmons expressly reserved his right to appeal both the denial of his motion to dismiss under the Speedy Trial Act, 18 U.S.C. § 3161 et seq., and the denial of his motion to suppress certain evidence. He was then sentenced to five years imprisonment and a three-year special parole term. For the reasons stated below, we remand for further findings on appellant’s Speedy Trial Act claim and affirm as to his remaining claims.
*530 I. Facts
On March 28, 1984, appellant Simmons and two others, Albert Thrower and Robert Moore, were arrested in connection with the sale of a small quantity of heroin to an undercover police officer. The following day, Simmons appeared before a United States Magistrate on a complaint charging him with possession of heroin with intent to distribute. The complaint was sworn to by arresting officer William Grogan, who asserted that the undercover officer told him the following: The undercover officer approached two men (Moore and Thrower) on the street and asked where he could buy “a half,” which is a package of heroin that sells for $20. The two men told the undercover officer to wait outside a game room while they went inside. The officer watched them go into the game room and engage in a brief conversation with Charles Simmons. (According to testimony elicited at the suppression hearing, the game room had both a glass window and a glass door.) Moore and Thrower then left the game room, returned to the undercover officer and handed him a glassine envelope containing what later proved to be heroin. Shortly thereafter, the undercover officer described Simmons, as well as Moore and Thrower, to officer Grogan. Grogan then went to the game room and arrested Simmons, discovering six glassine envelopes of heroin in Simmons’ possession.
Simmons was indicted in three counts on April 9,1984, subsequent to his appearance before the Magistrate. Accordingly, section 3161(c)(1) of the Speedy Trial Act mandated that Simmons’ trial begin within seventy days of April 9, unless time was excluded pursuant to 18 U.S.C. § 3161(h). On June 14, 1984, Simmons filed a pretrial motion asserting that he had been arrested without probable cause and that the heroin found in his possession and certain pretrial statements should therefore be suppressed. The speedy trial “clock” was thus stopped after sixty-five days had elapsed. 1 18 U.S.C. § 3161(h)(1)(F). The return date of the suppression motion was June 28; on June 29 the government requested and, with the concurrence of defense counsel, was granted until July 3 to file a reply. The government did not file its response until July 13, to which Simmons replied on August 1. On August 21, the government filed its response to Simmons’ August 1 letter.
One month later, at a pretrial conference held on September 21, 1984, the district court scheduled a hearing on the suppression motion for October 2. At the same conference, Simmons’ counsel stated his “intention to file a motion to dismiss for violation of the Speedy Trial Act.” After the parties orally recounted the timing of the relevant motion practice, the district court noted that “nobody moved like lightning, but nobody was really dragging their feet.” And while the court stated that it did not think the Act had been violated, it also suggested the possibility of “further discussion of a Speedy Trial motion” after the suppression hearing.
After an additional delay of a week at the instigation of the court for reasons unexplained in the record, the suppression hearing was held on October 9, 117 days after the motion to suppress was filed. Over defendant’s objection that the undercover officer should testify, the government presented the testimony of Grogan, the arresting officer. The defense called no witnesses in support of the motion, relying principally on an affidavit submitted by Simmons with the motion to suppress and on post-arrest statements made by Moore and Thrower exonerating Simmons. At the close of the October 9 suppression hearing, the district court denied Simmons’ motion, concluding that the arrest had been supported by probable cause.
*531 On October 10, the court and counsel further discussed the speedy trial question. Although both the court and the government apparently assumed that “four or five days” still remained on the speedy trial clock, the court never expressly denied appellant’s motion to dismiss. On October 12, Simmons entered a plea of guilty to Count Three of the three-count indictment, which charged him with possession of heroin with intent to distribute. He expressly conditioned his plea on the right to appeal both the denial of the suppression motion and the denial of the motion to dismiss under the Speedy Trial Act. Simmons was sentenced on December 7, 1984, and this appeal followed.
On appeal, Simmons argues that (1) he was not brought to trial within the time limits of the Speedy Trial Act and his indictment must therefore be dismissed; 2 (2) his arrest was not supported by probable cause and the district court therefore erred in denying his motion to suppress; and (3) the prosecutor “intimidated” potential defense witnesses, depriving Simmons of his due process rights.
II. Speedy Trial
When Simmons filed his motion to suppress on June 14, 1984, just five days remained on his seventy-day speedy trial clock. The motion was denied on October 9, 1984, and three days later, on October 12, Simmons entered his conditional guilty plea. Simmons’ speedy trial claim turns on whether the period from June 14 to October 9 is excludable pursuant to 18 U.S.C. § 3161(h)(1)(F), which excludes “delay resulting from any pretrial motion, from the filing of the motion through the conclusion of the hearing on, or other prompt disposition of, such motion.” If the entire period is excludable, as the government contends it is, then Simmons pled guilty on the sixty-eighth day of his speedy trial clock, and the Speedy Trial Act was not violated; if three or more days of that period are not properly excludable, however, Simmons was not brought to trial within the mandated seventy days and his indictment must be dismissed.
In
United States v. Cobb,
the period of allowable excludable delay applicable to a pretrial motion begins automatically with the making of the motion and runs for a period of time that is “reasonably necessary” to conclude a hearing or to complete the submission of the matter to the court for a decision. Under this view, long postponements of hearing dates, unless reasonably necessary, would not qualify as excludable time, nor would unnecessarily long extensions of time for the submission of papers.
Recognizing that many considerations, some not likely to be disclosed in the record, might induce the district judge to defer the suppression hearing, we held further that it is the district judge who must in the first instance determine whether under all the circumstances the period of delay was reasonably necessary for processing the motion. This conclusion requires us to reverse and remand to the district court for that purpose.

Unlike the determination that time will be excluded from the speedy trial clock based on the “ends of justice,” 18 U.S.C. § 3161(h)(8)(A), which we have held must be made prospectively,
see United States v. Tunnessen,
Here, as in
Cobb,
“[w]e do not mean to suggest that a specific determination must be made on each pending motion as to whether the time involved is reasonably necessary to bring it to hearing or other prompt disposition.”
III. Motion to Suppress
In concluding that appellant’s arrest had been supported by probable cause, the district court had in the record before it the following sequence of events: (1) the undercover officer had a conversation with Moore and Thrower in which he indicated his desire to purchase a quantity of heroin; (2) Moore and Thrower then took the undercover officer to the game room and told him to wait outside; (3) Moore and Thrower went into the game room and spoke with appellant; and (4) Moore and Thrower then left the game room, returned to the undercover officer and produced a package of heroin. The court expressly declined to rely on Grogan’s testimony that the undercover officer told Grogan that he saw Simmons pass Moore a glassine envelope. Viewed “practically and in a commonsense fashion,”
United States v. Travisano,
Against all this appellant denies participation in the transaction in question and notes that there was another man in the game room, apparently the storekeeper, who might have supplied the heroin to Moore and Thrower. According to appellant, Moore and Thrower first spoke with the storekeeper, who told them to play or leave the premises. Appellant claims that his only contact with the two men was simply to repeat the storekeeper’s instructions. But the only suggestion in the record that Moore and Thrower spoke to *533 anyone in the game room but appellant comes in appellant’s own affidavit. It would not have been improper for Judge Griesa to refuse to credit appellant’s self-serving statement; nor would it have been erroneous to find that, even if Moore and Thrower had spoken with the storekeeper, who apparently was behind a glass partition, there was probable cause to believe •that they had obtained the drugs from Simmons. The facts relied on by Judge Griesa were sufficient to constitute probable cause. Accordingly, the motion to suppress was properly denied.
IV. Prosecutorial Misconduct
Appellant’s final claim is that his conviction should be reversed because the prosecutor engaged in “impermissible intimidation of the defendant and his potential witnesses.” Specifically, appellant claims that the prosecutor intimidated Moore and Thrower into not testifying by warning them, through counsel, that they would be committing perjury if they testified so as to exonerate appellant and that any peijury would meet with punishment. Citing
Webb v. Texas,
We have repeatedly held that the entry of a conditional guilty plea preserves only the specifically mentioned issues and waives all other nonjurisdictional claims.
See United States v. Pinto-Mejia,
For the foregoing reasons, the judgment of the district court is affirmed in part and remanded in part for further findings.
Notes
. In calculating the clock’s 70 days from indictment to trial, neither the date of the indictment nor the date on which a motion is filed is counted.
See United. States v. Severdija,
. Citing the factors enumerated in 18 U.S.C. § 3162(a)(2), appellant argues that the indictment should be dismissed with prejudice. In view of our decision to remand this portion of the case for further findings, we need not now address this contention.
