> There is a bug in how we check for whether the daughters mentioned in parent
> region are present in .META. The check is done when we are processing a
> server shutdown. We're making the mistake of checking for presence of the
> daughter in the list of regions that used to live on the crashed server BUT
> fact of the matter is is that the daughter could just as well be rebalanced
> to another server.
> The upshot is that we are inserting into .META. and trying to assign regions
> that are already assigned.
