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.

Thank you,
