| 7 * This is a regression test for the bug that the interval timer | |
| 8 * is not initialized when _PR_CreateCPU calls PR_IntervalNow. | |
| 9 * The bug would make this test program finish prematurely, | |
| 10 * when the SHORT_TIMEOUT period expires. The correct behavior | |
| 11 * is for the test to finish when the LONG_TIMEOUT period expires. | |
