If these handlers run Lisp or call primitives or their subroutines, it's a
tough requirement, which is almost impossible to fulfill.  The resulting
build will be very fragile.  Emacs internals signal errors all over the
place.  You could catch errors via internal_condition_case_* etc., but doing
so will sometimes trigger an infinite loop of errors, and make Emacs
unresponsive.
