> Kernel test ThreadTest.testInterrupt_Terminated() fails intermittently when invoking isInterrupted() for a terminated thread.
> Possibly join(), interrupt() and isInterrupted() are poorly synchronized.
> I attached the test which demonstrates the issue. Usually I have the output as follows on linux x86 2CPU machine:
> 108 FAILED: terminated thread has not been interrupted
> 138 FAILED: terminated thread has not been interrupted
> 206 FAILED: terminated thread has not been interrupted
> 475 FAILED: terminated thread has not been interrupted
> 549 FAILED: terminated thread has not been interrupted
> 553 FAILED: terminated thread has not been interrupted
> 576 FAILED: terminated thread has not been interrupted
> 693 FAILED: terminated thread has not been interrupted
> 730 FAILED: terminated thread has not been interrupted
> 741 FAILED: terminated thread has not been interrupted
> 765 FAILED: terminated thread has not been interrupted
