-------------------------------------------

+1, although I don't think it's going to be included in 0924 unless the RC's sunk.

> During rolling restarts, we'll occasionally get into a situation with our 100-node cluster
where a RS stop takes 5-10 minutes.  The problem is that the RS is undergoing a compaction
and won't stop until it is complete.  In a stop situation, it would be preferable to preempt
the compaction, delete the newly-created compaction file, and try again once the cluster is
restarted.
