I guess we can't do this for the C-level DEFUN's (without massive
changes), but we might be able to check some timer before executing a
Lisp function or something.  However, wouldn't such a new check risk
slowing Emacs down as a whole?

IOW, I ask if what you ask for is a little bit "too nice", and if we
shouldn't just fix the problematic ELisp code itself to use a progress
reporter or something to that effect.
