> Since the change to async logger, this test fails 100% of the time for me locally. [~steve_rowe] confirmed that it fails for him too so it's not something weird in my environment.
> Why there are no reports from Jenkins of this failure is a mystery.
> The _test_ succeeds, but there is a thread leak and the stack trace points to "lmax.disruptor" which is certainly a part of the async logging.
> And why, if this is something generic, it doesn't fail many many tests is another mystery so I suspect it's something specific to the test, perhaps having to do with mocking the metric reporter, but that's a wild shot in the dark.
> My working hypothesis is that "something isn't being closed/shutdown correctly", but that's...a little vague.
