Can you point me to this? I can't seem to find it. (Unless you meant it in an abstract sense.)

Do variable view distances actually change the number of chunks loaded? I was under the impression that was fixed at 17x17 chunks, regardless of how many fewer chunks the client requests. (I was also under the impression that clients could not set a view distance higher than 17x17 chunks, but I'm no expert.)

Performance doesn't look terrible, though I suppose it could be improved by checking against a `Set` of chunks in use.
