I've uploaded a new version of a barrier synchonization primitive to 
http://groups.yahoo.com/group/boost/files/thread_barrier_v2.zip

Changes/Issues:

1.  HTML documentation included.
2.  "generational_barrier" variant renamed to barrier.  This will be 
the primary barrier in the package.
3.  "barrier" variant renamed to one_shot_barrier.  This may be 
dropped from the package as it is a limited version of #2 w/o much 
compensating efficiency/functionality.
4.  Both barrier variants now return a "BOOST_SERIAL_THREAD" value to 
exactly one thread upon return from wait().
5.  Behavior is still undefined if the barrier is destroyed while 
some threads are still in wait().  Once Boost.Threads cancellation 
mechanics are solidified, I think that barrier should cooperate 
gracefully with cancellation and that this will address many of the 
same needs that an exception throw from wait() would accomplish.

Comments welcome.

Thanks,
Dave
