    Description

      Currently, the synchronization for CachingStrategy is a little inconsistent. DFSOutputStream#setDropBehind modifies the strategy object, but there's nothing protecting that object against concurrent use in createBlockOutputStream. Similarly, DFSInputStream#setDropBehind is synchronized, but not all the uses of cachingStrategy are.
