> The kernel test ThreadTest.testInterrupt_Waiting() fails intermittently with the message "waiting thread has not received the InterruptedException". 
> This is easily reproduced on 2CPU x 4 core machine but happens much more rarely on 2 CPU machine. I usually see the failure on Windows 2003 2CPU x 4 core.
> The attached test shows up the issue.
> Some threads which are in the TIMED_WAITING state don't get InterruptedException in reasonable time (5 sec in the attached test). The test needs WAIT_CONDITION_TIME to be set nearly the same as THREAD_WAIT_TIME to pass.
> Threads which are in the WAITING state don't get exception at all (intermittently).
