 add a completion function associated to the class barrier


 {{{
     class barrier
     {
     public:
         barrier(barrier const&) = delete;
         barrier& operator=(barrier const&) = delete;

         barrier(unsigned int count);
         template <typename F>
         barrier(unsigned int count, F&&);

         ~barrier();

         bool wait();
         void count_down_and_wait();
     };


 }}}
