 Steps:
 1. Set up a handler for signal SIGABRT, such that it is called if 
signal is ever raised.
 2. Call sighold on that SIGABRT.
 3. Raise a SIGABRT and verify that the signal handler was not called. 
Otherwise, the test exits with unresolved results.
 4. Call sigrelse on SIGABRT.
 5. Verify that the handler gets called this time.
