 * Test that timers are disarmed and deleted by an exec.
 *
 * Steps:
 * 1.  Set up a timer
 * 2.  Call execl to sleep for a few seconds
 * 3.  If timer does not interrupt the execl, it will return success.
 *     If it does interrupt, or if execl fails, return failure.
 *
 * For this test, signal SIGTOTEST will be used, clock CLOCK_REALTIME
 * will be used.
