// MacAsyncSocket is a kind of AsyncSocket. It only creates sockets
// of the TCP type, and does not (yet) support listen and accept. It works
// asynchronously, which means that users of this socket should connect to
// the various events declared in asyncsocket.h to receive notifications about
// this socket.
