It probably should be possible with some caveats:
- memory allocated by Python is never passed into the library such that
it also ends up being subject to boehm-gc;
- memory allocated by the library is never used by Python objects.
So memcpy()ing between library allocated and Python allocated memory
would seem to be a way to achieve this.
I would call GC_INIT in the extension's import routine
(init<module_name>()) for a C extension, and immediately after loading
the library if using ctypes.
