Oh, and as I didn't actually run it, I have no idea about what performance
is really like. I assume you've done lmbench runs across wide variety (ie
UP to SMP) of machines with and without this?

"Scalability" is useless if the baseline you scale from is bad. In the
end, the only thing that matters is "performance", not "scalability".
Which is why sometimes O(n) is better than O(logn).
