Three strikes them out

[Lennart Borgman (gmail)]

Sometimes I am able to get fontification to loop. That may lock Emacs 
totally.

It would be good to have some way to stop timers from running in such 
situations - if it helps, I am not sure. Maybe three C-g in a row

  C-g C-g C-g

would be a good convention for stopping all timers (and not let them 
start again)?

But I am not sure if it is possible to implement something that can stop 
the timers. Is it possible?
