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

[~apurtell] Lets see.  I don't think it a blocker being a long-standing issue.  
It does seem to make bucketcache problematic in hot read when doing lots of 
evictions case.  Wonder if our [~zjushch] has tripped into this issue.  Not 
sure I've fixed it yet either.  It is looking good but want to let it run a 
day.  Takes a while to run out of heap.

> Testing BucketCache, my heap filled after running for hours. Dumping heap, 
> culprit is the ramCache Map in BucketCache.  Tried running with more writer 
> threads but made no difference.  Trying to figure now how our accounting is 
> going wonky.
