Are you by any chance writing code that tends to have catch-all
"except" clauses?

If so, then the KeyboardInterrupt might be getting swallowed by one of
those (or require you to hit Ctrl-C more than once to get past one or
more exception handlers and then actually terminate the application).

Or, if you have a top level application exception clause that is
intended to help keep the application running even in unexpected
circumstances, you may need to special case KeyboardInterrupt and
terminate or re-raise it to terminate.
