> hbase-1892 made splits faster.  This issue is about making them faster still.
> Chatting w/ some bright lads down south, and because Ryan has been going on about it
for a year now, on split, we should just open the daughter regions on the parent's RegionServer.
 Don't even bother telling master about the split just happened.  Let the balancer rectify
uneven region distribution.  Requires smarter load balancer first, one that can at least recognize
the special case of a fresh unloaded cluster with bulk upload running.  In this case it would
balance differently than it would on a laden cluster.
