I think you are wrong about suspend making no sense on GUI terminals:
we have (in Emacs 23) suspend-frame that does work on GUI.

Anyway, the examples I gave were just that: examples.  Here's another
example: we have make-frame-on-display, make-frame-on-tty, and
make-terminal-frame; and then we have make-frame that can do all of
the above.  IMO, it's terribly confusing.

But again, maybe I'm the only one who is confused.  My confusion is
exasperated by the fact that I cannot find any useful methodical way
to describe all these functions with partially overlapping
functionality in the ELisp manual.  Suggestions welcome...
