There's always "kill -9", no?

Which part?

Is it even possible? On a text terminal, we configure the terminal to
generate SIGINT when C-g is pressed, and that's why we can provide
this feature: if we see a nested SIGINT, we know the user pressed C-g
more than once without Emacs being able to handle it. But in a GUI
session, this is impossible, AFAIK.
