stack resolved HBASE-2405.
--------------------------

    Resolution: Fixed

Opens and closes are done by executors now.    By default regionservers have 3 
opener handlers (with one extra each for meta and root).   Configuration can up 
or down the number.  Splits are not yet done by executors nor compactors and 
flushers but thats coming in a different issue.

Closing as fixed by HBASE-2692

> Close, split, open of regions in RegionServer are run by a single thread only.

> JGray and Karthik observed yesterday that a regoin open message arrived at 
> the regionserver but that the regionserver worker thread did not get around 
> to the actually opening until 45 seconds later (region offline for 45 
> seconds).  We only run a single Worker thread in a regoinserver processing 
> open, close, and splits.  In this case, a long running close (or two) held up 
> the worker thread.  We need to run more than a single worker.  A pool of 
> workers?  Should opens be prioritized?
