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