Skip that question....of course, python23.dll goes into c:\windows\system
so it wasn't where I was searching...

I'd still be very interested in examples of use through ctypes (with
which I'm not yet familiar).

Alex' slides were interesting, but I think they might reflect a subtle
trend away from Python's traditional treatment of programmers as
consenting adults, with all the concern about newbies and the hints
that such a dangerous feature will be abused to no end.

The slides also suggest that there are almost no use cases whatsoever 
for such a feature, though admitting there might, just barely, be enough
to merit adding it as a non-newbie C-only API which one has to jump
through hoops (or use ctypes :-) to access.  

I can think of several use cases right off the top of my head, one 
of them being while running automated unit and acceptance tests, 
to ensure that a test involving threads will complete (generally 
with a failure in this case) even if the code is broken and the 
thread cannot be terminated.
