    One could also approach this from the opposite side -- slapping (the
    equivalent of) `save-buffer-excursion' around the timer functions

That would be one way to implement it for all the functions that can
run timers, including accept-process-output, read-event and
read-key-sequence.  Still, the question is, is it ok to make the change
that timers can't change the current buffer.

Can anyone think of a situation where this would be a problem?  Would
someone like to look through the code base and see if any timer needs
to change the current buffer?
