bug#4093: Overlay keymap and timers

[Mihai Bazon]

Actually, it seems it hasn't anything to do with overlays:

(defun my-set-keymap-with-timer ()
  (interactive)
  (run-with-timer 0.5 nil (lambda()
                            (use-local-map my-keymap)
                            (message "Done setting keymap"))))

If we eval the following and M-x my-set-keymap-with-timer, the keymap
will only be enforced after the first keypress (i.e. first press of M-n
says "M-n is undefined", but subsequently it works).

Found another thread about this issue here:

Stallman says "we should consider that a serious problem". ;-)
