What exactly do you mean by "when Emacs is idle"? The loop is in
wait_reading_process_output and I thought that this is "kind of"
executed when Emacs is idle. Or do you refer to idle timers? I tried
to analyze the call graph starting from command_loop. I must be missing
something... Is there yet another concept of "idleness" in Emacs?
