> When a new region server is brought online, the current balancer kicks off a whole bunch
of region moves and causes a lot of regions to be un-available right away.  A slower balancer
that gradually balances the cluster is probably a good script to have.  I have an initial
version that mooches off the region_mover script to do this.
