Servers causing 0 FPS on client with chests.

This bug happened on a bukkit server however a server should not be able to cause your FPS to drop to 0. After closing a chest inventory, if the server fails to notify the client the chest has closed the client will freeze on 0 FPS for around 10 seconds. I have not tested this on 1.5.2 but I could not see a similar issue on the bug tracker.
