However the failure was still observed on select machines. This change addresses the remaining failures by ensuring that any new WatchKey is held until the polling thread becomes active.

The Windows pre-test failure is related to `runtime/ParallelLoad/SuperWait/SuperWaitTest.java` and should not be related to this change. Windows as a native library based implementation and does not use the one provided by PollingWatchService.
