Hello,

v13: 
http://www.boostpro.com/vault/index.php?action=downloadfile&filename=boost-threadpool.v13.tar.gz&directory=Concurrent%20Programming&

after the discussion yesterday I've modified the code. Now the pool can be 
configured (second template argument of tp::pool) to use recursive invokation 
of tasks or fibers in order to enable fork/join semantics.

I've found that the recursive invokation is more than two times faster than 
using fibers (see examples recursive_fibonacci_recursive_task.cpp and 
recursive_fibonacci_with_fibers.cpp).
The code using fibers sometimes raises an assertion in ~mutex() (used in 
work-stealing queue).
For this reason and following the discussions I think I'll remove the support 
for fibers from threadpool.

regards,
OPliver
