    Problem Summary TSD4U.00054 The test may fail on implementations because the test does not accumulate enough process time before timing out.
    Problem Text
    The test may fail on implementations because the test does not
    accumulate enough process time before timing out.

    line 14:
    According to the X/OPEN man pages for setitimer:

    ITIMER_VIRTUAL decrements in process virtual time. It
    runs only when the process is executing. A SIGVTALARM
    is delivered when it expires.

    Since the test does not accumulate enough process time, the
    test timed out (if we increase the timeout, the test passes).

    In summary,
    This is a test error. The recommended code change is to add
    code in the following loop to accumulate more process time:

    while ((now_time - st) < ((double)TOTAL_TIMER_SET + 20.0))
    {
    if (sig_recvd_flag)
    return;
    now_time = get_time(ITIMER_VIRTUAL);
    for (i=0; i< 10000; i++)
    j++;
    }

    Test Output
    1 SECTION: Discrete Tests

    3 TEST CASE: setitimer
    4
    5 TEST PURPOSE #8
    6 A call to int setitimer(int which, const
    7 struct itimerval *value, struct itimerval *ovalue)
    8 when which is ITIMER_VIRTUAL shall decrement the timer
    9 in process virtual time and deliver a SIGVTALRM signal
    10 to the calling process when the timer expires.
    11 PREP: Set the timer to a known value
    12 TEST: setitimer() for ITIMER_VIRTUAL generates the
    13 SIGVTALRM signal after timer expiration
    14 ERROR: Timed out waiting for timer to expire
    15 SIGVTALRM was not delivered
    16 8 FAIL
