 There is a bug on the code of shared_mutex::try_lock_upgrade_until. The
 following change fixes it.

 {{{
          template <class Clock, class Duration>
          bool try_lock_upgrade_until(const chrono::time_point<Clock,
 Duration>& abs_time)
            boost::mutex::scoped_lock lk(state_change);
            while(state.exclusive || state.exclusive_waiting_blocked ||
 state.upgrade)
            {
 -              if(cv_status::no_timeout ==
 shared_cond.wait_until(lk,abs_time))
 +              if(cv_status::timeout ==
 shared_cond.wait_until(lk,abs_time))
                {

 }}}
