One word of caution: extract does not seem to check for NULL pointers. 
PyImport_AddModule never returns NULL, but other functions do.  E.g., I
was using PyImport_ImportModule and when it can't find the module, it
returns NULL.

To work around that, I use handle<> on the very first call like that,
then initialize an object and stick with Boost.Python calls afterwards.

Thanks again for the help :)
