This brings back the option that the Spigot version of netty saw. By default Netty will try and use cores*2 threads, however if running multiple servers on the same machine, this can be too many threads. Additionally some people have 16 core servers. If 32 Netty threads are allowed in this setup, then the lock contention, and thus blocking between threads becomes much greater, leading to decreased performance.

The problem here is that MinecraftServer.save(..), will attempt to sleep whilst all pending chunks are written to disk, however due to various and complicated bugs, it will wait for an incorrect amount of chunks, which may cause it to sleep for an overly long amount of time. Instead we will mimic the save-all command in its behaviour, which is both safe and performant.
