Erm, OK, it's not yet defined, but I think this is the intention, Peter
explicitly working on it and IIUC he already "donated"
boost::shared_ptr's code to the GCC people. Maybe my formulation wasn't
very good.

I hope it's OK if I address these issues here, with the boost
implementation only as an example (or reference implementation) but also
looking at the larger picture of intended behavior and guarantees of
what should be standardized in the future.
