* Fixed a major memory leak in packet processing - PacketQueue.Close is never called, causing the PacketQueue for dead clients to be preserved (including it's contents). 

* This patch is highly experimental and may cause clients to not be able to connect, if this is the case, it will be rolled back in approximately 5 minutes.
