I think that's the wrong question.  The right question is how probable
is it that the user presses C-g to abort a timer function that just
happens to run at this very moment.  I think the answer is "extremely
improbable".  It is much more probable that C-g was meant for
something else, some activity that is much more evident to the user.
Like getting out of the minibuffer after deciding that the command
does not need to be invoked after all, for example.
