To have rsync act as a daemon but use the existing connection, pass both
--daemon and --server (as in the remote shell command sent by the
client, which you can see with -vv).  --daemon alone may have worked
previously if rsync's stdin was a socket, which triggers an "inetd mode"
similar to what happens if you also pass --server.
