why are we trying to built thread-safety into shared_ptr? There is good saying that drove C++ to the point where we are right now: "do not pay for what you do not use". If I'm willing to provide own synchronization for shared pointers, or use it in single-threaded env, why would I need to pay extra heap allocation to make it play nice in mt world? Moreover, if I'm willing to use shared_ptr in mt env. and use its synchronization features, it does not provide synch. for pointee anyway. Thus I still need to provide my own synchroniozation to protect state of pointee. B.
