> Running some tests, I set hbase.client.scanner.caching=1000.  Dataset has large cells.
 I kept OOME'ing.
> Serverside, we should measure how much we've accumulated and return to the client whatever
we've gathered once we pass out a certain size threshold rather than keep accumulating till
we OOME.
