    (Ref. UniSoft: err.4.2.3.074)

    While testing fcntl with a command of SETFL to test that including
    O_NOCTTY has no effect, this test fails with child timed out
    for the following reason.

    The test initially sets up the controlling terminal etc correctly.
    The same process opens both ends of the loopback terminal. It then
    sends an interrupt character to one end (using write) and expects
    itself to be interrupted. The process uses pause to wait for this
    signal; however, the signal may already have been caught before the
    return from the write system call. Write may not return EINTR
    because the data may have already been transferred to the
    terminal (which is almost certainly the case because it is this
    that causes the interrupt in the first place). In this case the
    program has already caught the signal and pause will never be
    interrupted.

    A fix could be to use a separate process to send the interrupt
    with some additional validation to ensure synchronisation.
    Test Output

    Child process timed out
