I like this idea; even though it doesn't solve all cases (e.g. closing 
gracefully after a successful boot), it does solve some and it has a negative 
code size cost (-11 bytes).

I have committed a similar patch:

This is functionally slightly different to your patch, in that it will match 
the current behaviour by exiting immediately if a key other than Ctrl-B is 
pressed.  This allows interactive users to skip the (usually extremely 
irritating and unwanted) prompt message by pressing other keys.
