That's so, and Ctrl+Break on Windows is passed to the app's SIGBREAK handler
(this signal is available from current Windows Pythons via signal.SIGBREAK;
Unix doesn't have such a signal; then again, Windows doesn't have most Unix
signals).  Ctrl+Break kills immediately because that's what the system
default handler does, and Python doesn't override the default SIGBREAK
handler on Windows (user Python code can override it, but I don't recommend
it!).
