Comment (by tscrim):
Okay, let's revert back to having `UniqueRepresentation` because it will
work as a session/variable manager. I don't think we should spend a lot of
time doing that as we can hack around it (even though it is in effect what
we are doing/should do). I don't like it because it is a hack, but it
seems like the best option for now. Unless you want to directly use
Python's multiprocessing with shared memory for the corresponding parents
to avoid pickling, which I would still somewhat prefer in a way so we
don't have to do this hack. (Multithreading in Python has shared memory,
but unfortunately it can't run on multiple processors because of the GIL.)
Anyways, I leave the decision up to you.
