The situation is not that simple or I'd have used blocking reads on 
getch() -- which presumably tells DOS I'm not busy.

The problem is detecting mouse events too.  The only way I've seen (and 
others have concurred) is a busy loop that checks for the mouse state 
and whether a key has been hit with kbhit().
