Oh goody, a sarcastic comment which doesn't actually bother to explain the bug :)
Since what I describe is basically WeakReferenceable, it's not obvious to me that there's a bug. I tell you when the thing to which your Remote(Weak)Reference points is destroyed, just like weak references invoke finalization callbacks. If you try to invoke remote methods after than happens I just return you an error. What's the problem? This is exactly how weak references work.

your app is broken.
That's a really good point. Only CPython destroys objects deterministically when the ref count hits zero.
