| 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. |
