    Test Suite VSRT version 5.0.3
    Test Identification rt.os/mqueue/mq_send 5
    Problem Summary TSD4R.00012 This test leaks memory descriptors.
    Problem Text

    This request addresses the following two cases:

    /tset/rt.os/mqueue/mq_send/T.mq_send 5
    /tset/rt.os/mqueue/mq_receive/T.mq_receive 4

    Both these tests leak message queue descriptors. In our implementation, a
    process may have no more than 32 open memory queue descriptors.

    The failure with errno set to EMFILE is correct according to XSH5, p. 538.

    The fix is to close the descriptors at the appropriate places:

    tset/rt.os/mqueue/mq_send/mq_send5.c
    576a577
    > mq_close(mqd1);
    586a588
    > mq_close(mqd1);
    593a596
    > mq_close(mqd1);
    601a605
    > mq_close(mqd1);
    607a612
    > mq_close(mqd1);
    621a627
    > mq_close(mqd1);
    628a635
    > mq_close(mqd1);
    634a642
    > mq_close(mqd1);
    638a647
    > mq_close(mqd1);
    640a650
    > mq_close(mqd1);



    tset/rt.os/mqueue/mq_receive/mq_receive4.c
    551a552
    > mq_close(mqd1);

    > mq_close(mqd1);
    578a582
    > mq_close(mqd1);
    585a590
    > mq_close(mqd1);
    591a597
    > mq_close(mqd1);
    595a602
    > mq_close(mqd1);
    597a605
