Timeout at 1on1

What about a function to pause the game for some secs? Players could make a bind, when pressing a button both players freeze and cant move till the player presses the button again.

So where is the advantage? Let´s say you have lags, your mom is talking to you, someone writes you a message in icq...
Players could not do chaatkill any more and, what is more frequently, some ppl run around and gather items while you can´t. That´s unfair but with a timeout function it would have an end.
