How does RAII deal with reference loops? It is trivial to create a loop of owned pointers in memory that never decrement, and it isn't that unusual of a pattern not to be a concern. Just curious; I used a combination of strong/weak reference counting when I dealt with this. It wasn't fast, but it did appear to be less prone to implicit leaking.
