> One of our engineers got a weird TableExistsException in his code and I see 
> that the client-side logging says the table was deleted in less than a second 
> while it took the master 5 seconds to do it. Doing code inspection, the 
> .META. scanner in HBA.delete can set _found_  to _true_ and then set it back 
> to _false_ in the case where the deleted table isn't the last one. We should 
> just do a scan that would get the rows specific to the table instead of 
> scanning *all* the rows.
