8  *  Test that the sigpending() function stores the set of signals that
9  *  are blocked from delivery.  Steps are:
10  *  1)  Block three signals from delivery.
11  *  2)  Raise two of those signals.
12  *  3)  Verify that the two signals raised are shown via sigpending.
13  *  4)  Verify the one signal not raised is not shown.
