If a server enables Anti Xray, packet sending can be delayed until the
chunk has been obfuscated, blocking the entire queue from going out.
On a busy server, considering Anti Xray can only operate on a single
thread, it is quite possible the obfuscation backlog can get quite behind
resulting in a delay of sending packets.
And logging in is a clear area where lots of chunks are going to be queued
for obfuscation....
We should probably special case a few more than this (such as chat),
but this will hopefully help the keep alive issues some people run into.
