> Currently we are not tracking the heap usage of block indexes.  We're just relying on the fact that we leave a large percentage of total heap as part of "everything else" not in memstores or the block cache.  The "everything else" portion should be left for ephemeral/transient memory usage, not long-lived objects like block indexes.  Introduction of blooms will extend this issue to meta blocks in general.
> All of this should be moved into an LRU.  Either the existing block cache LRU or a new LRU.
