Bug ID: 55493
           Summary: ntdll:threadpool - test_tp_timer() sometimes fails in
                    Wine
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll

ntdll:threadpool - test_tp_timer() sometimes fails in Wine:

threadpool.c:1439: Test failed: WaitForSingleObject returned 0
threadpool.c:1441: Test failed: WaitForSingleObject returned 258

See https://test.winehq.org/data/patterns.html#ntdll:threadpool

So instead of getting a timeout then a success, the test first gets an
unexpected WaitForSingleObject() success and then a timeout. That means it's
not a simple issue of the test running too slow.
