Sorry, I didn’t catch that it stops completely. Still, there’s nothing wrong with stopping the ma’aseh of closing the door, so if you think there’s no problem with pulling the hand away, you could do it yourself, with a chair, or even your own hand. Just close the door enough (l’shitoscha) so that it would close in its own, but not enough for the light to go off, then move your own hand away.
I don’t see why a second person is maaleh or morid, unless you’re looking for shnayim sheasuhu as a snif.
I guess you’re just going to have to move to Austin, Tx. 🙂
