I looked into the underlying C function 'socket_shutdown' (in file
runtime/Clib/csocket.c).
It calls shutdown first and contains a comment by Manuel:
      /* MS: 19 Aug 2008, we don't have to close fd */
      /* since it will be closed automatically with */
      /* SOCKET( sock ).input                       */
I don' understand the comment because the C shutdown
call comes before any hooks or similar.

In my code, I use this pattern:
(socket-close s)
(socket-shutdown s)
