    Problem Text


    This problem has previously been recognized as a grey area in the
    XPG3 specification and has not changed in XPG4. A permanent waiver
    was granted.

    POSIX 1003.1-1990 states on page 135 line 280 and XPG4 System Interface
    Defintions, Issue 4 on page 118 section 9.1.11 that "The last process
    to close a terminal device file causes output to be sent to the device
    and any input to be discarded". VSX tests this in the case that output has
    previously been suspended by a call to tcflow(), in which case it expects
    that the close will allow output to be restarted. A question has been raised
    as to whether this is required in these circumstances or whether it is
    admissable for the data to be discarded.
