Tic-TACS is a very experimental reimplementation of Minecraft's engine for asynchronously generating and loading chunks with significantly less overhead as well as bringing the ability to operate safely over multiple threads.
The name "tic-tacs" comes from the Minecraft class ThreadedAnvilChunkStorage (TACS for short) under Yarn. This is the monolithic class responsible for most of the asynchronous processing work, and it is known for being very chaotic.
