 * Test that timer_settime() will return ovalue.it_interval = the previous
 * reload value.
 * - set up a timer to expire in TIMERSEC seconds with reload value RELOADVAL
 * - set up a new timer
 * - ensure ovalue.it_interval = RELOADVAL
 *
 * For this test, signal SIGCONT will be used so that the test will
 * not abort.  Clock CLOCK_REALTIME will be used.
