 *  Test that the sigtimedwait() function shall return the selected signal
    number upon success.

    Steps:
    1. Register signal SIGTOTEST with the handler myhandler
    2. Block SIGTOTEST from the process
    3. Raise the signal, causing it to be pending
    4. Call sigtimedwait() and verify that it returns the signal SIGTOTEST.
