It's not been done yet, but Boost.Threads had it's interface designed
to support co-operative threading models. The boost::thread::yield()
method is the key to this. I can't, however, comment as to whether
this was enough to allow MacOS native co-operative threads for the
implementation. And writing portable code to work on platforms that
use both models will be tricky even if the interface supports it.

It would be great to see this done.
