Subject: [PATCH] Asynchronous chunk IO and loading
# UPDATE NOTES: RegionFileStorage and SectionStorage need resolving (will conflict on apply)
# ChunkSerializer needs the new tick lists to be saved (see added todos)
ChunkSerializer needs the new tick lists to be saved (see added todos)
This patch re-adds a file IO thread as well as shoving de-serializing
chunk NBT data onto worker threads. This patch also will shove
