---------------------------------------------
Hey! :)
Publishing one more patch (here and on RB) with code review comments fixes so
far.
Thank you [~eshcar] and [~anoop.hbase] !!!
[~ram_krish], I'll wait to your review a bit, but I would like to finish with
this JIRA asap and move forward.
I have spent a bit too much time on this debugging...
Thanks!

> Because MSLAB list of chunks was changed to list of chunk IDs, the chunks
> returned back to pool can be deallocated by JVM because there is no reference
> to them. The solution is to protect pool chunks from GC by the strong map of
> ChunkCreator introduced by HBASE-18010. Will prepare the patch today.
