Not using something that is not needed, sure. But the directory access will 
ever need to use the tree, no matter what, and since it releases the playlist 
properly, I don't see the problem. There is no circular dependency. You just 
cannot destroy the playlist until the directory plugin has not completed 
reading its directory (which is a set of non-blocking operations).
