> CompactionExecutorTest has a race between the runnable/callable under test completing
> and the {{afterExecute}} method stashing it for the test.  Replace the wait/sleep loop
> with a {{SimpleCondition}} that is signaled once the test task throwable has been recorded.
> This seems fairly hard to hit but has happened on CI.  It took about 2600 iterations on my MacBook to trigger, but you can artificially hit frequently by adding a sleep at the start of the afterExecute method.
