Before I do that... there's something I failed to notice before: the 
frame *does* get resized, in a sense. At least X seems to think so, but 
Emacs doesn't.

Notice the white area of the same height as the child frame hiding the 
text in the parent frame on the attached screenshot. Also note that the 
yellow background didn't help: the area is white.

This only happens with xterm.diff applied, never without it.
