We need to create some relationship between the unbound method and the 
class. So the class has a reference to the unbound method, and the unbound 
method has a reference to the class, thus creating a cycle. Bound methods 
don't come into it - it's the unbound method that's the problem.

I'm struggling to think of another, not too complicated name that conveys 
the same information.
