 *  Assertion 4 - that raise() is equivalent to kill(getpid(), sig); is
 *  essentially tested implicitly via assertion 1.
 *  This test is the reverse test case:  Test assertion 1, but replace
 *  raise() with kill(getpid(), sig).  It should pass if assertion 1
 *  passes.
 *  1) Set up a signal handler for the signal that says we have caught the
 *     signal.
 *  2) Call kill(getpid(), <signal under test>)
 *  3) If signal handler was called, test passed.
 *  This test is only performed on one signal.  All other signals are
 *  considered to be in the same equivalence class.
