I thought I had, but Oh shucks, apparently not, and I *knew* that as well,
how embarrassing!
In any case as Alexander pointed out it doesn't completely help due to the
priority inversion problem, there's a good description of the issue here:
http://www.netrino.com/Publications/Glossary/PriorityInversion.html. It can
be worked around, but by the time you've done that, you may well have just
have used a mutex and let that handle the thread priorities for you (the
previously posted mutex version can be improved upon however, as can the
existing Boost.Thread code).
