PER CURIAM.
The petition to vacate our order of August 28, 1959, is denied by the court sitting en banc. Upon reconsideration we find that the application for leave to appeal was timely inasmuch as it was made to us within 10 days of the order of the district judge that contained the 28 U.S.C. § 1292(b) statement. Because in our judgment the grant of leave to appeal will not fulfill the purpose expressed in the statute, we, in our discretion, adhere to our previous decision denying leave to appeal.
