All,

I've been wondering about the use of CTRL-C regarding timers.
There has been a lot of discussion on ways to regain control in
the face of a runaway timer, which is of course an important
consideration.  I've been wondering, however, about any negative
effects of accidental cancellation.  If I understand correctly, when
a user presses CTRL-C while a timer happens to be running, that
timer will be canceled and not rescheduled.  Can this happen
accidentally when the user is pressing CTRL-C for other reasons
(e.g., to abandon an ex-mode command he was typing)?  Since
timers might be running at arbitrary times, how can a user be
sure it's safe to press CTRL-C without running the risk of canceling
a timer by mistake?  Should it require multiple CTRL-C presses in
a row before aborting current and future timers, or is there some
other way to make sure the user won't accidentally cancel timers
that are operating properly?
