Forgive me for chiming into a discussion I wasn't following about a
subject that I'm mostly ignorant about, but: when the display property
goes away, Emacs triggers a redisplay the next moment it doesn't have
anything more important to do.  That redisplay should supply you with
an event to remove the gtk widgets, no?  Just plug your
widget-removing routines into the code that runs during redisplay.
