I think I fixed that one, now. Thanks you.
It was indeed linked to the "timer run is not in timer-idle-list"
situation, and it was indeed an instance of the scenario where an
earlier timer cancels a later timer.
The trick is that the earlier timer is "code that runs sit-for", since
it means that this earlier timer also runs all other timers (via
sit-for).
And removing the copy of the timer list does help, but doesn't solve the
problem: even if we don't copy the list, while running timer A, we'll
keep a pointer to the rest of the (uncopied) list; and this pointer may
point to a cons cell that gets removed from the list by cancel-timer.
