One possibility is the buffer is killed while timer-idle-list is
temporarily bound to nil, in this case the timer will be left in the
timer-idle-list and causing this error.
The code in rng-valid.el uses the following idiom to redisplay without
triggering idle timers.
(let ((timer-idle-list nil))
....
(sit-for 0)
....)
Is there a way to do this without let-binding timer-idle-list?
