But won't self->args point to a broken object while any callbacks triggered by
Py_XDECREF() are run?
An alternative would be
tmp = self->args;
self->args = args;
Py_INCREF(self->args);
Py_XDECREF(tmp);
As far as I can see the idiom Py_?DECREF(self->...) is rarely safe outside of a
deallocator unless you are sure the pointed to object has a "safe" type (or you
are sure the refcount cannot fall to zero).
