FYI, there are 534 calls to sit-for in *.el files.

It seems hard to try to understand for each of these calls whether
non-Lisp event are _intended_ to interrupt it or not.

BTW, 134 of those calls are (sit-for 0), which most likely are intended
to do a redisplay, so for clarity, they could be replaced by (redisplay).

Maybe some calls to sit-for may actually wait for process output; in which
case they should really be calls to accept-process-output.
