> FineGrainedAtomicHashMap supports fine-grained locking in pessimistic mode, but in optimistic mode the write-skew check is still done for the entire map.
> The write skew check should be done for each entry of the map individually, so that multiple transactions can update the same FineGrainedAtomicHashMap at the same time.
