lock-free

Herlihy and Shavit's book (The Art of Multiprocessor Programming) solution to memory reclamation uses Java's AtomicStampedReference<T>;.

To write one in C++ for the x86_64 I imagine requires at least a 12 byte swap operation - 8 for a 64bit pointer and 4 for the int.

Is there x86 hardware support for this and if not, any pointers on how to do wait-free memory reclamation without it?
