Boost::thread passes its function object around several times by value,
so it gets coyp-constructed and destructed several times. I had the same
problem, and used some sort of proxy-class until I realized that
boost::bind creates exactly that kind of proxy-objects. So either use
boost::bind or boost::mem_fn or std::mem_fun.
