condition_variable class , method wait_for in linux broken.
wrong recalculation of time leeds to exeption generating
It take place because the result
line 403 : req.tv_nsec += static_cast( (sec - static_cast(sec))*1e9 );
may exeed 1e9 nanosec
what makes
line 421: pthread_cond_timedwait( &my_cv, lock.mutex()->native_handle(), &req ) .....
return errno 22 ( Invalid param ) and than throw an exeption
fixing patch is:

Good luck
