Then there's a bug, because an idle timer should only fire when there's no other input. If there's keyboard input, Emacs should process it first. I don't think the bug is related to the fact that the timer handler re-schedules itself. That is something many timers do. There's something else at work here, and that something is most probably on the C level.
