> Spawning this from HBASE-2375, I saw that it was much more efficient 
> compaction-wise to check if we can split right after flushing. Much like the 
> ideas that Jon spelled out in the description of that jira, the window is 
> smaller because you don't have to compact and then split right away to only 
> compact again when the daughters open.
> Another thing it improves is while we're normally waiting for the compaction 
> to happen, data that's still coming in will make us go way past the 
> MAX_FILESIZE to a point where for the first region I was seeing a store size 
> 3-4x bigger before it was able to split.
> I targeted this for 0.94, but I'd like to get this into 0.92.1 or .2 too.
