The cause for Stefan's traceback looks quite clear: Connection_createaggregatefunction() release the GIL (through the PYSQLITE_CON_CALL macro) before calling into sqlite3_create_function_v2, which itself calls the destructor for the old aggregate function, aka. apsw_free_func(), which calls Py_DECREF without re-acquiring the GIL. So apsw needs to sanitize its callbacks implementation here.
