Just to be sure, are you concerning about sync and propagation delay of memory contents including lock variables between cpus? IMHO, it makes no difference. It's a true dependence once the dependency is viewable by a cpu, which means anyway it actually happened. And please remind all locks related to crosslocks are serialized via proper memory barriers. I think this was already descibed in my document. Is there something I missed? Please let me know.
