    Problem Text




    The TSD5TH.00041 is incomplete for the full solution of detecting the
    delivery of signals for threads.

    Sigwait test 2 tests the following assertion:

    Signals generated for the process shall be delivered to exactly one of
    the threads waiting in a sigwait() call for the signal or not blocking
    the signal.

    When the sigwait() thread receives the signal, the test code is not recording
    that the signal was received and the thread id for the thread which received
    the signal. The signal handler is not executed for this condition.

    Solution follows:

    *** sigwait.c Tue Mar 31 11:21:47 1998
    --- /tmp/sigwait.c.fix Mon Apr 6 10:02:25 1998

    {
    --- 609,618 ----
    {
    vsth_surprise("sigwait", 0, rval, &T2_errors);
    }
    ! if (T2_sig == SIGALRM) {
    ! T2_tid = pthread_self();
    ! ++T2_nsigs;
    ! }
    }
    else
