 * Test to see if timer_getoverrun() returns -1 and sets errno==EINVAL when
 * trying to call timer_getoverrun on a timer that has been deleted or not.
 * Since this assertion is a "may," either option is a pass.
 *
 * For this test, signal SIGCONT will be used, clock CLOCK_REALTIME
 * will be used.
