> Well, in the previous revision I was adding a MutationSet to an
ExecutorService that had an unbounded queue and 1 thread. That's not immediate
Yeah, its certainly not immediate. However, it probably much less than
1ms between adding to thread pool and thread calling run() on Runnable (when
thread is idle). Relative to ~250ms, its like kinda immediate.
> Can MutationSets be binned concurrently?
I have no idea. Could not say yes w/o much more review of the code than I
want to do late on a Fri afternoon :). I suspect something would blow up.
