    Problem Summary TSD4C.00221 This test may fail because multiprocessor scheduling may result in the ed.hup file being checked for existence before the file is created.
    Problem Text
    This test may fail on implementations because multiprocessor
    scheduling may result in the ed.hup file being checked for existence
    before the ed process has created the ed.hup file and exited.

    In this test, an expect process starts an ed session, sends a SIGHUP
    to the ed session and then checks to see if the ed session creates the
    necessary ed.hup file.

    The outcome depends on whether ed process has control after the SIGHUP
    is sent or if the expect process has control. On a multiprocessor
    system, processor scheduling order of the two processes makes this an issue.

    When the expect process has control, it finishes and the shell script
    immediately checks for the existence of the ed.hup file, possibly
    before the ed process had time to create the ed.hup file and exit as
    it should.

    When the ed process gains control first, the ed.hup file gets created
    before the main test tries to check for the file.
