Review comment:
I wonder if these `getBoundedCachedThreadPool` methods could be replace
to calls to methods directly on `java.util.concurrent.Executors`. I think we'd
need to evaluate on a case-by-case basis how the resulting pools are being used
and if they're constructed to correctly match the use-case.

Review comment:
This is a bizarre instantiation, don't you think? keep-alive of 500
seconds? in a test? Maybe this can be just
`Executors.newSingleThreadExecutor()`.
