13 *  Test that the sigwait() function.
14 *  If prior to the call to sigwait() there are multiple pending instances of
15 *  a single signal number (and it is implementation-defined that the signal
16 *  number DOES NOT support queued signals), then there should be no remaining
17 *  pending signals for that signal number.
18 *  Steps are:
19 *  1)  Block a signal that doesn't support queueing from delivery.
20 *  2)  Raise that signal 4 times.
21 *  3)  Call sigwait()
22 *  4)  Verify it cleared the signal from the pending signals and there
23 *      are no signals left in the pending list.
