Stalling does do something.

If you are on the bubble, and have no real chance at making the final table (say, you have enough to play one round when the BB will put you all in), stalling will often get you into the money.

Yes, it is poor ettiquite, and I have never done it, but if stalling is a +EV move, and 2+2ers are all about +EV, why not do it?
