Comment (by viboes):

 The code in develop (or >=boost.1.58) contains now

 {{{
 #if defined BOOST_THREAD_PROVIDES_FUTURE_CONTINUATION
             void do_continuation(boost::unique_lock<boost::mutex>& lock)
             {
                 if (! continuations.empty()) {
                   continuations_type the_continuations = continuations;
                   continuations.clear();
                   relocker rlk(lock);
                   for (continuations_type::iterator it =
 the_continuations.begin(); it != the_continuations.end(); ++it) {
                     (*it)->launch_continuation();
                   }
                 }
             }
 #else
             void do_continuation(boost::unique_lock<boost::mutex>&)
             {
             }
 #endif
 }}}


 Please could you give a try?
