-// 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::bind to specify the completion handler:
-//
-// +---------------+
-// | |
-// | receive |
-// | |
-// +---------------+
-// |
-// async_- | +----------------+
-// receive() | | |
-// +--->| handle_receive |
-// | |
-// +----------------+
-//
-// 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.
