[boost] [threadpool] relation with TR2 proposal

Hello, I learnt yesterday that there is a TR2 proposal for a thread_pool, sponsored by our Boost colleague Anthony Williams: http://www2.open-std.org/JTC1/sc22/wg21/docs/papers/2007/n2276.html What is the relationship with this proposal of the threadpool library that is being discussed these days here at the Boost list? Thank you, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
