---------------------------------------

Filed HBASE-12976.
(By the way that is recent realization I had when testing garbage collection 
vs. network performance)


> [Ergonomics] hbase.client.scanner.caching is dogged and will try to return 
> batch even if it means OOME

> 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.
