Expected Behavior

Exploring the world in a server (in multiple dimensions) would not create large amounts of long (haha) long[]s that were referred to by CachedGridEntry.CachedChunkData that would stick around in memory.

Actual Behavior

Here is an actual example of a heap dump generated from one of these:

Note that most memory is taken up by long[]s, and halfway down, we start seeing these:

Steps to Reproduce

Load a Supersymmetry server (maybe a client instance)
Move around a while
Perform heap dump
Analyze using VisualVM

Additional Information

This may require a refactor of world generation, which already was in need of one.
