> BoundedConcurrentHashMap.EvictionListener should have a bulk entry listener so that CacheStores can optimize passivation behavior.  Current BoundedConcurrentHashMap notifies EvictionListener for every evicted entry.  However, as you see from BoundedConcurrentHashMap.Segment.attemptEviction(..), eviction often happens in bulk. If these evicted entries are supposed to be passivated, it is often beneficial to begin a transaction because it often takes much less time to call commit() less often.  If N entries are evicted:
> without bulk eviction:
>     store.store(e1); -- each store implied a commit()
>     store.store(..);
>     store.store(eN);
> with bulk eviction:
>     store.begin(mods(e1, ..., eN), tx, true);
