Rather than "breaking the cycle" we try to not have the cycle in the first
place.

Typically what we do is create some kind of weak reference. There's no built-in
weak reference mechanism, but there are lots of examples where we keep a
pointer that the pointed-to object is aware of, then when it's torn down (or
destroyed) it tells the object that's pointing to it that it's gone.
