Indeed, thanks. In any case, we have 2 problems with the current code: - We have two completely different implementations: sit-for ELisp and sit_for in C. - The ELisp version uses read-event and then tries to unread the event, which is frought with too many perils. I don't really care whether sit-for is implemented in ELisp or C, but we should only have one implementation (it's hard enough to get it to work once). And the implementation shouldn't read+unread.
