> Currently KeyValueHeap is used for both, heaps of StoreScanners at the Region level as well as heaps of StoreFileScanners (and a MemstoreScanner) at the Store level.
> This is various problems:
>  # Some incorrect method usage can only be deduced at runtime via runtime exception.
>  # In profiling sessions it's hard to distinguish the two.
>  # It's just not clean :)
