* 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.
