LGTM
I've actually been thinking about having better thread pooling here with a
RejectedExecutionHandler which
* increments a statistic
* hands on to ThreadPoolExecutor.CallerRunsPolicy
So rather than do blocking when the pool is full, fall back to executing in
the current thread. Goal: when the pool is full we still get useful work done
because the current thread is doing it.
I worry about this though when it comes to things like RenameOperation; is
the use of CompletableFuture<> creating expectations in the code that the work
will actually be done by a separate thread.
How about we merge this patch in as this, and then look at that problem in
more detail.
