------------------------------

Thanks for the review.

We used to do 'stopping'.  Smile.

'Stopping' gets us closer to classic Lifecycle.

I think just needed for this at mo.

> Starting and stopping clusters I see that an open directive can come in while we are
shutting down all the user space regions on a particular regionserver.  Regionservers will
only shut themselves down after all user space regions have closed.  We queue up all the closes
at a particular time.  If an open comes in while we are in the closing condition, then the
regionserver won't go down.  The region open needs to be blocked.
