Done, I've just implement my idea. I change the some implementation, actually the main problem is on DiskFileItem, but I need to change several classes too. No more writing file to disk, but write as Entity, big file chunk into several entities. Original FileCleaner will launch daemon thread, but I use simple loop to clean up the unreachable PhantomReference on every request.
