 *  Test that the killpg() function shall send signal sig to the process 
    group specified by prgp.
    Steps:
 *  1. Set up a signal handler for the signal that says we have caught the
 *     signal.
 *  2. Call killpg on the current process group id, raising the signal.
 *  3. If signal handler was called, test passed.
