 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.
