The main problem with this is that the existing data structures are, well, there. You can't replace them without breaking all existing Python code, i.e. without basically inventing a new language. If that's required for removing the GIL, I doubt that it will ever be done. Stefan -- http://mail.python.org/mailman/listinfo/python-list
