Ban is not immediate

[GrantBartlett]

Banning a player from a game is not immediate.

Steps to reproduce:

1). Host kicks user
2). User rejoins within 2-3 seconds

After 2-3 seconds the user isnt' able to join the game.

I'm not sure what the communication looks like for IRC on this one, but the client of the user that is kicked/banned is obviously aware that the kick/ban took place. Perhaps, the client just has an in memory list of game IDs they cannot join? Assuming there is simply a delay occurring here, by the time they restart the client to clear the in mem list, the actual ban will be in place by IRC.
