-// This class manages socket timeouts by running the io_context using the timed
-// io_context::run_for() member function. Each asynchronous operation is given
-// a timeout within which it must complete. The socket operations themselves
-// use boost::lambda function objects as completion handlers. For a given
-// socket operation, the client object runs the io_context to block thread
-// execution until the operation completes or the timeout is reached. If the
-// io_context::run_for() function times out, the socket is closed and the
-// outstanding asynchronous operation is cancelled.
