Tom> ISTM unnecessary to increase the reference count for each Py_RETURN_NONE use. I mentioned this in the bug, but for the record on the list, I think this patch will not work for versions of Python before the immortality changes. In particular if a gdb method returns a new reference, it means the caller is free to decref the reference. However this series changes gdb to assume that the decref will not happen for certain objects. thanks, Tom
