I've investigated several reloading frameworks, including the
ones you mentions as well as http://code.google.com/p/reimport/
The approach of using the gc to remap references seemed to
have the fewest overall limitations, but requiring C API changes
is a big downside. I'm going to have to do a more detailed
comparison of the features offered by each approach.

Is there a trick to doing it this way, or are you suggesting
building a ctypes wrapper for each C type in the Python
library, and then effectively reimplementing tp_traverse
