The resulting set shall be the signal set pointed to by set
Steps:
1. Have main create a new thread and wait for its termination.
2. Inside the new thread, set up the signal mask such that it contains
only SIGABRT (by passing SIG_SETMASK value to pthread_sigmask)
4. Raise SIGABRT, and make sure that the handler associated with it
wasn't executed, otherwise fail.
5. Also make sure that SIGABRT is pending, otherwise fail.
* patch *
5b. Change mask to SIGUSR1 and check that the handler is called. This means
that SIG_SETMASK removed the old signal from the set.
* /patch *
6. Pass one of three return codes to the main() function:
- A value of -1 if SIGABRT wasn't found pending or
causes the handler to be executed.
- A value of 0 if SIGABRT was in fact pending and the handler
wasn't executed.
- A value of 1 incase of any UNRESOLVED situation such as an
unexpected function failure.
