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