> TestZooKeeper fails on occasion.  I caught a good example recently.  See below failure
stack trace.
> It took me a while.  I thought the issue had to do w/ our recent ipc refactorings but
it looks like a problem we have always had.  In short, MetaScanner is not handling DoNotRetryIOEs
-- it is letting them out.  DNRIOEs when scanning are supposed to force a reset of the scan.
 HTable#next catches these and does the necessary scanner reset up.  MetaScanner is running
some subset of what HTable does when it is scanning except the part where it catches a DNRIOE
and redoes the scan.  Odd.
> TestZooKeeper failed in this instance because the test kills a regionserver at same time
as we are trying to create a table.  In create table we do a meta scan using MetaScanner passing
a Visitor.  The scan starts and gets a RegionServerStoppedException (This is NOT a DNRIOE
-- it should be -- but later we convert it into one up in ScannerCallable).
> DNRIOEs are thrown to the upper layers to handle....
> Let me look into having MetaScanner just use HTable scanning.  It makes an instance just
to find where to start the scan... let me try using this instance for actually scanning.
> TODO: Do this convertion everywhere a DNRIOE could come out.
