Sure, that's true. But I still maintain that responding to ^C is an
important property of the system. If you have to do some more
complicated set of steps like the ones you propose here, a decent
number of people aren't going to figure it out and will end up
unhappy. Now, as it is, you're unhappy, so I guess you can't please
everyone, but you asked for opinions so I'm giving you mine.
