[boost] non-intrusive weak_ptr example?

All the examples I've been able to come up with where I want a weak_ptr
also lead naturally to wanting shared_from_this()... well, actually,
weak_from_this(). The basic paradigm is that a member function is used to
add owned objects which need a back-pointer. Inside a member function you
have a raw pointer, not a shared_ptr, regrettably.

Is there an example which maps naturally onto non-intrusive use of
weak_ptr?
