    Problem Summary TSD4R.00008 This test may fail where a system takes a while to complete its aio_read requests.
    Problem Text
    The test failed because a timeout is set to too short a value. Making
    the change:

    vsx4/tset/rt.os/aio/aio_read/aio_read.c
    1663c1660
    < sleep(4);
    ---
    > sleep(2);

    allows the test to pass.

    Test Output
    We have the following failure only on x86

    /tset/rt.os/aio/aio_read/T.aio_read 6 Failed

    Test Description:
    If _POSIX_ASYNCHRONOUS_IO is defined or the implementation supports
    the aio_read() function as described in System Interfaces and Headers,
    Issue 5:
    On a call to aio_read() when aiocbp->aio_sigevent.sigev_notify is
    SIGEV_SIGNAL the signal specified in aiocbp-
    >aio_sigevent.sigev_signo shall be generated for the process when
    the operation completes.

    Review Information

    Review Type TSMA Review
    Start Date null
    Completed null
    Status Complete
    Review Recommendation No Resolution Given
    Review Response
    As this test allows at least 40 seconds for the system to complete 50
    small reads this seems curious. However as there is no requirement
    on aio performance in the spec we recommend a TSD be granted.

    Review Type SA Review
    Start Date null
    Completed null
    Status Complete
    Review Resolution Test Suite Deficiency (TSD)
    Review Conclusion
    This is an agreed Test Suite Deficiency.
