Perform the check in act.movement.c the same way you check if a room is a 
dt, check if the player is supposed to fall....  ie, if !IS_AFFECTED(ch, 
AFF_FLY) or whatever...

I have a similar thing, for scatter traps, the instant a player walks in 
they are forced to leave by a random exit.  The interesting application 
is rooms that are all scatter trapped, with only one exit.. down.. giving 
a "falling" sequence before a dt at the end :)
