?One
thing that should be on the todo list is to review the usage of memory
barriers. ?I don't think they are serving the purpose that you think
they are.

All of those are from Peters original implementation, I never use any
barriers so they actually looked alien to me. Unless I get a clear
rationale from Peter I'll just remove them all for the time being in
the fix-up version due after updating to generic slave control.
