-Subject: [PATCH] Disable Explicit Network Manager Flushing
-
-This seems completely pointless, as packet dispatch uses .writeAndFlush.
-
-Things seem to work fine without explicit flushing, but incase issues arise,
-provide a System property to re-enable it using improved logic of doing the
-flushing on the netty event loop, so it won't do the flush on the main thread.
-
-Renable flushing by passing -Dpaper.explicit-flush=true
