    Problem Text
    There is a problem in msgsnd.c in that it checks that the child process
    has suspended, kills it with a SIGUSR1, tidies up and returns. The child
    process catches the SIGUSR1 signal and exits. Unfortunately, the parent
    process returns to tet_fork (called from cpsig) and sends a SIGTERM to
    the child process before it has had time to exit after receiving the
    SIGUSR1. This results in the test reporting "UNRESOLVED".
    The problem would be solved by the parent process giving the child
    chance to exit before returning to tet_fork. Perhaps this should be
    done by waiting for the child to exit, timing out if this has not
    happened before WAITTIME has elapsed.
    Test Output
    ************************************************************************
    /tset/XPG4.os/ipc/msgsnd/T.msgsnd 2 Unresolved

    Test Description:
    When there is insufficient space in the queue or the system to send
    the message pointed to by msgp and the IPC_NO_WAIT flag is clear in
    msgflg, then a call to msgsnd(msqid,msgp,msgsz,msgflg) suspends the
    calling process.

    Test Information:
    unexpected signal 15 (SIGTERM) received
