The attached patch optimizes the current implementation of enable_shared_from_this, it saves one plain pointer. That might not be very much, but it's a start. It is 100% compatible for the users, no features are dropped. Further improvements might be possible, but I think the attached patch is a good base.
I believe it would be possible to replace _internal_shared_this and the shared_ptr inside the deleter wrapper with a single shared_count.
That would be the next logical step, but it is not as easy as replacing the weak_ptr. Which is why I try to get as much of the other patches in before attacking this idea, it should make it easier once the patches to discuss become smaller. Regards, Daniel
