So, this right away leads you to sync_socket and async_socket.  What if the
read/write operations (ones that make the distinctinction between
sync/async) were factored out?  Then you would have a socket class to create
socket endpoints and manipulate
associated options, and (a)synchronicity would be defined by the operations
applied to this socket.
