oh yes, this is a problem. i will probably change the sshd-X11-proxy
from internet to unix domain sockets.

libX is broken if i set DISPLAY=localhost:x.y and ignore any
X cookies.

I tried this before, but it does not work since it uses AF_INET6 if
i connect by
	$ ssh -X ::1

so it's not really acceptible. I'm still looking for a better
solution...
