I'm thinking I should augment the patch so as the observable behavior
of (sit-for 0) doesn't change. It would no longer run timers if only
input-pending-p changes as described. Currently:
(defun sit-for (seconds &optional nodisp obsolete)
[...]
(cond
[...]
((input-pending-p)
nil)
((<= seconds 0)
(or nodisp (redisplay)))
[...]
I considered whether (<= seconds 0) could fall through to the t case
instead. The read_char function has a complex implementation, so it's
not clear doing so wouldn't change behavior.
Is there another Lisp function that does timer_check and little else,
which the (<= seconds 0) case could call? Should I write a new subr
for it?
Looking ahead to the concurrency branch, should (sit-for 0 t) and
(thread-yield) have different behaviors? Or perhaps the former calls
the latter? I don't see thread-yield checking for timers to run,
should it? (And it didn't look like timers were split out into their
own threads on the concurrency branch.)
