Analyzing a heap dump, I saw that LinkedList of HRegionServer took up
noticeable space - namely 4 chunks of 5MB each.
Here is related entry from refguide:
The number of resevoir blocks of memory release on OOME so we can cleanup
properly before server shutdown.
I wonder if we can reduce the size of resevoir blocks.
