8 This program verifies that sigpause() removes sig from the signal mask.
9
10 Steps:
11 1. From the main() function, create a new thread. Give the new thread a
12 a second to set up for receiving a signal, and to suspend itself using
13 sigpause().
14 2. Have main() send the signal indicated by SIGTOTEST to the new thread,
15 using pthread_kill(). After doing this, give the new thread a second
16 to get to the signal handler.
17 3. In the main() thread, if the handler_called variable wasn't set to 1,
18 then the test has failed, else it passed.
