-  X <weasel> it would be nice to support a unix socket for the control thing.
-    The main motivation behind this was that we could let unix permissions
-    take care of the authentication step: everybody who can connect to the
-    socket is authenticated.  However, the linux unix(7) manual page suggests
-    that requiring read/write permissions on the socket in order to use it
-    is Linux specific, and that many BSD-derived systems ignore the permissions
-    on the socket file.  Portable programs should not rely on this feature for
-    security, therefore the motivation for this feature is gone.
