Inhibit-modification-hooks gets let-bound *all the time* by things like
font-lock, after-change-functions, etc...
I see two ways for that variable to become globally non-nil:
- a braindead package uses `setq' on that variable.
- you bang on C-g enough that you end up hitting the infamous
race-condition on unwind-protect (and let unbinding): unwind-protect
forms get run when exiting because of C-g, but if you hit C-g while
running those unwind forms, they may not run to completion, so you can
end up with some of those unwind forms being "not run" (or only partly
run). I guess we could try to inhibit-quit while running the unwind
forms to try and circumvent this problem, but such a change could
introduce new bugs (if an unwind-form takes a long time to run,
i.e. expect to be run without inhibit-quit).
Of course, there could also be a third way, but I can't imagine what
that would look like.
