The only way to lookup weak references to functools.partial objects is with weakref.getweakrefs. I don't know if it's normal for extension types that define tp_weaklistoffset to not add a __weakref__ descriptor, but I figured at the very least a subtype specifying "__weakref__" in its __slots__ could get one. Instead, it fails with the partially true TypeError: __weakref__ slot disallowed: either we already got one, or __itemsize__ != 0.
