> With our current global secondary indexing solution, a batched Put of table
> data causes a RS to do a batch Put to other RSs. This has the potential to
> lead to a deadlock if all RS are overloaded and unable to process the pending
> batched Put. To prevent this, we should use a higher priority queue to submit
> these Puts so that they're always processed before other Puts. This will
> prevent the potential for a deadlock under high load. Note that this will
> likely require some HBase 0.98 code changes and would not be feasible to
> implement for HBase 0.94.
