    Problem Summary Parent process in getrusage 3 does not wait long enough for child
    to finish busy work.
    Problem Text The problem with this assertion is the parent does not wait long
    enough
    for a child process to do some busy work. The relevant code is in
    the
    file: TET3.3h/vsx/tset/CAPI.os/procenv/getrusage/getrusage3.c in the
    function subtest3():

    if (WAIT_EVENTN(CHILD_DONE, (5*MAX_TIME_TO_RUN)) == -1)
    {
    tet_result(TET_UNRESOLVED);
    return -1;
    }

    MAX_TIME_TO_RUN is a calculated constant based on the vsxspeed value
    (1=fast, 10=slow), it is 3 + 3*SPEEDFACTOR. For a speed factor of 3,
    MAX_TIME_TO_RUN is 12 seconds, and the above code thus waits for 60
    seconds. The actual time which the child code took was approximately
    200 seconds.

    Changing the speed factor for this machine to get a wait time of 200
    seconds would mean setting vsxspeed to 12, which is not possible and if
    it were, would be too slow for the other tests which use this value.

    Extening the parent's wait time does not fix the problem because
    doing so for slower machines causes the test to take so long the
    harness
    assumes it is hung. Decreasing the child's work load seems to be the
    correct solution.
