I'd just like to encourage this effort. Where I currently work lock
performance is a big issue, and no we don't have any small repeatable
tests - yet. Most of the tests have been real system tests and do not
lend themselves to simple comparisons and also before my time...

What I would say is that I will certainly be looking at Phil's code and
trying it out. From what I know in other parts of our code base, where
performance really counts, we use futexes.

So I'd really like to see this in boost::thread even if it is a
preprocessor option.
