stack commented on HBASE-2457:
------------------------------
.bq ...could we simply make it so that it checks whether there are currently
flushes blocked on a compaction, and if that's the case, force one to happen?
Thats not easy given current structure.
Here's a second cut at a band-aid. This differs from first in that we'll
compact the last 4 files in the list at a minimum. Review please. I'm testing
it now.

> Testing 0.20_pre_durabil...@934643, I ended up in a state where one region

> was with a special config with very low flush threshold in order to stress
> test flush/compact code.
