Interesting. Yes, it seems limited in that you get CTRL+C or
CTRL+BREAK which seems to map to one of CTRL_CLOSE_EVENT,
CTRL_LOGOFF_EVENT, or CTRL_SHUTDOWN_EVENT signals.  

If someone is interested in hooking this into pydb's signal handling
mechanism, I'll consider adding in a future release. (If hacking the
configure script to test for the presense Microsoft Windows or the
win32api is tedious, I can manage doing that part.)
