[boost] [thread] Could mutex and condition_variable be movable?

Hi, I'm defining a class that is non copiable but movable. The class contains a boost::mutex and boost::condition_variable fields which are non copiable neither movable. I'd prefere not been forced to allocate all the class data in a pointer to make possible the move operation. Has a sens to make these classes movable?
