While this is not binding, it is considered common courtesy if you are the last person to do a turn, to wait 5 minutes until the game has processed and sent you a new turn, and send that turn in as well. That way you are not always the last one to delay hosting.

All other things being equal, some players base their decisions on who to go to war with by who is holding up the game. I kid you not.
