> Currently, when the HRegionServer runs out of the memory, it will call master, which
will cause more heap allocations and throw a second exception that it's run out of memory
again. The easiest & safest way to avoid this OOME storm is to abort the RegionServer
immediately when it hits the memory boundary.  Part of the 89-fb to trunk port.
