Aka (unless (memq (car-safe last-input-event)

Huh?  `run-with-idle-timer' is not supposed to generate any event.

Running mouse avoidance after focus-out does not seem very useful, so we
should filter out focus-out elsewhere than here.

What means "showing the Window List"?

I don't know what this is talking about either.

Shouldn't `switch-frame' be ignored for similar reasons, then?
