That one is too fragile I agree. If "special" means `C-g C-g C-g' then
that is fine in my book. If something gets stuck and doesn't respond
to one "abort this" command, I usually tend to try several times
anyway, and suspect this is the same for a lot of people.

It seems to have some effect with `C-g' after some time. But still
doesn't abort it, only shows some warning, yet doesn't make Emacs
responsive.
