There's definitely precedence for that, and I think you could argue
that a KeyboardInterrupt isn't an error the same way SystemExit and
StopIteration aren't errors. I worry about backwards compatibility,
but I'll add this to the UPITS[1] Exception PEP 
(Does anybody else lament the lack of an inheritance diagram in the
exceptions module documentation?)
