8 *  Test that the sigtimedwait() function shall return the selected signal
9    number upon success.
10
11    Steps:
12    1. Register signal SIGTOTEST with the handler myhandler
13    2. Block SIGTOTEST from the process
14    3. Raise the signal, causing it to be pending
15    4. Call sigtimedwait() and verify that it returns the signal SIGTOTEST.
