getset_descriptor cannot access `__objclass__`
It looks like a getset_descriptor has an
__objclass__ (as seen with
dir), but it's not available as an attribute.
__objclass__ is very useful in maintaining a pointer to the descriptor's class. For example, given an
__objclass__ attribute, one could pickle a descriptor... and thus make a broader class of objects available to multiprocessing, parallel, and distributed computing. (I'm the
dill author, and this is a huge blocker for people using

__objclass__ attribute be made available as a pointer to the descriptor's class? It seems like a bug that
__objclass__ is missing.
