Calling boost::asio::io_service::run from a std::thread

There are two ways as I have known, one is to create std::thread by lambda.

std::thread run_thread([&]{ m_io_service.run(); });

Another is to create boost::thread with boost::bind

boost::thread run_thread(boost::bind(&boost::asio::io_service::run, boost::ref(m_io_service)));
