Hi all,

A small update here:

This turned out to be a red herring, so please ignore this bit. I had a 
code path that failed to call Py_INCREF on Py_None which was held in a 
PyObject that was later Py_DECREF'd. This had some interesting 
consequences, and not surprisingly led to some double-frees. ;)

I was able to get much further with this fix, although I'm still having 
some trouble getting multiple interpreters running together 
simultaneously. Advice and thoughts still very much welcomed on the rest 
of the email. :)
