Another thing is that it's impossible to use custom add_ref() and release() for an owner the way it is done in intrusive_ptr. I mean a developer of a class must choose one of the shared_ptr and intrusive_ptr (if the last is extended to support a smart member pointers). But we want this class to be used inside owner of any type. And one owner will live with just *delete me* but another owner will require *let me do some processing and then delete me myself*.

Can't *let me do some processing and then delete me myself* be done with a custom deleter argument to shared_ptr? I.e. with the CTOR:
template<class Y, class D> shared_ptr(Y * p, D d): px(p), pn(p, d) { detail::sp_enable_shared_from_this( pn, p, p ); }
Ok. Agree. But what about custom add_ref()? Oleg Fedtchenko BoostOleg@yandex.ru http://boostoleg.narod.ru/member_ptr.html recommended thread entry http://lists.boost.org/MailArchives/boost/msg73168.php
