On: Notes on Lock Free Programming

Sure, but even with MESI a CAS translates into an exclusive lock on the cache line by a single core no?

I probably could have articulated my original question better, sorry.

I guess you could call holding a cacheline in the exclusive state the same as holding a lock. The difference, I think, is that there's an hard upper bound on response time on serving any remote request for sharing.
