You shouldn't have to store 2 function pointers for every intrusive_ptr object. You should only have to store 2 function pointers per instance pointed to, and then 1 reference to some shared structure in each intrusive_ptr object. Much like shared_ptr currently does.
You'd still need a pointer in every intrusive_ptr object to point at the shared_structure, plus you'd have to do dynamic allocation of the shared object. That is never going to fly. - From the "main reasons to use intrusive_ptr" section of its documentation: "The memory footprint of intrusive_ptr is the same as the corresponding raw pointer;" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkpSExoACgkQ5vihyNWuA4UXtwCeOYuF/Jdap1ajhsd7rI0e9bYa wY8AoMxu8bHr8+brBAMq+cGF+Ndkt2Nb =WNH1 -----END PGP SIGNATURE-----
