The idea of a dedicated method is to introduce the "10msec timeout
before showing the menu". It would be ugly to say "for this event the
host is going to wait 10msecs, for this other event it is not going to
wait".

Since we introduce a new method, getting the result from the return
value rather than waiting for a signal feel more efficient.
