Half-close is required for the protocols where one of the sides closes its
sending side and expects the answer, but it keeps the socket of the side which
has already closed the connection in CLOSE_WAIT state. Use -C to close both
sockets as soon as any of the sides closes the connection, -C1 to request
the default behaviour explicitly.
