I totally think you should be using 'set tty'.  It's the only way to
keep inferior and GDB output straight, and nobody has ever had the
forbearance to explain the drawbacks to me.

I still think it's odd that you would actually want a way to send a
SIGINT to either the inferior if running or GDB otherwise.  But if you
really do want that, then making GDB deal with it seems like the right
thing.
