- sufficient to break any of the four Coffman conditions for a deadlock. We'll solve this by requiring
- the ChunkMap CS for all SocketThreads operations before they lock the PluginCS - thus creating a kind
- of a lock hierarchy. However, this incurs a performance penalty, we're de facto locking the chunkmap
- for each incoming packet. A better, but more involved solutin would be to lock the chunkmap only when
- the incoming packet really has a plugin CS lock request.
- Also, it is still possible for a packet to slip through - when a player still doesn't have their world
- assigned and several packets arrive at once.
