Tried that between 4.2.0 and 4.2.1 -- doesn't work on Linux (anymore),
neither as user nor as root:

$ /proc/17773/exe -r
zsh: permission denied: /proc/17773/exe
# /proc/17773/exe -ls
zsh: permission denied: /proc/17773/exe

:-(

So I'll likely have to extend the according patch to also try to talk
with a 4.1.0/4.2.0 screen.

                Kind regards, Axel
