Note since python 3.0 (and PEP 3121), the PyModuleDef structure has some members like m_traverse, m_clear and m_free for this very purpose. So far, nobody cared to implement these methods for any module. Maybe one should start at least for static PyObject* that contain references to modules. -- Amaury Forgeot d'Arc _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
