Thanks very much, Ronald!

Not sure I understood all that, but I know where to dig now...

I see this in the comments in Modules/main.c:

I had thought this was a trivial matter, but now I see that it is a  
bit involved.

Our application already sets up the Python interpreter from a C++  
wrapper, so I suppose we already have a place to add hooks. Hmm.

If I come up with anything simple and clever, I'll post back to the  
list.

(If I come up with something embarrassing and stupid, maybe I'll keep  
it to myself...)
