Kirk Lund commented on GEODE-5662:
----------------------------------
ExecutorServiceRuleTest.singleThreadedByDefault is also flaky. It's caused by
awaiting maximum of 30 seconds for submitted tasks to countDown a
CountDownLatch. The CPU has to be very overloaded to hit these failures.

> This test failed in CI. To me it looks like this test seems to be assuming
> that if it schedules two tasks they will actually run concurrently, which may
> or may not happen depending on timing.
