I'm still running the same test (in-place upgraded cmogstored a few
times to fix some bugs), and haven't hit these warnings again
(constantly pushing around 20GB/s total).

I forget to mention cmogstored is multithreaded and idle clients
automatically migrate between threads when becoming active (using
EPOLLONESHOT), so maybe this tickles some rare race condition
somewhere...

I probably won't be in a good position to reboot/test patches until
Tuesday, though.
