> Looking at thread counts reported by the nice 'after:' log message, I see the likes of
TestReplicationKillSlaveRS and all of its derivatives reporting hundreds of threads (shows
as over 1000 in one run here).
> Running the test standalone, I see the above run up the threads to 700 (only!). Need
to figure why the discrepancy.
> The attached patch makes some difference -- cutting down the client thread count -- but
not enough. Let me look more.
