 * This is a regression test for the bug that the interval timer
 * is not initialized when _PR_CreateCPU calls PR_IntervalNow.
 * The bug would make this test program finish prematurely,
 * when the SHORT_TIMEOUT period expires.  The correct behavior
 * is for the test to finish when the LONG_TIMEOUT period expires.
