> Ryan apparently said this 6 months ago, that on split, the regions are 
> assigned back to the parent hosting regionserver almost always.  Then, to 
> keep up some kinda balance, the load balancer kicks and closes the just 
> opened daughters -- which have just been opened a moment ago -- to deploy 
> them elsewhere in the name of keeping good balance.
> This issue is to confirm the above behavior indeed happens and then to take 
> action to make it so at least one of the daughters is held up so it doesn't 
> go back to the current heartbeating host, the parent hosting server.
