Hi, now that we have Boost.Container and Boost.Thread (trunk) uses Boost.Move, boost::thread_group has less sense. I was thinking on replacing it by some generic algorithms as join_all, interrupt_all that work with generic containers so that the user can use the best containers adapted to her own needs. typedef boost::container::vector<boost::thread> thread_vector; { thread_vector threads; for (int i = 0; i < 10; ++i) { threads.push_back(boost::thread(&increment_count)); } join_all(threads); } { thread_vector threads; for (int i = 0; i < 10; ++i) { threads.push_back(boost::thread(&increment_count)); } interrupt_all(threads); } Could boost::thread_group be deprecated once these generic algorithm are released? Or, is there something really useful on the thread_group class that needs to be preserved or even improved? Best, Vicente
