Black voodoo still as to why and how mserver5 reads the contents of .gdk_lock 
via filedescriptor 0.

I guess, automatic merovingian tests are still out of reach (for now?),
right?

A fresh look just made me realise that merovingian didn't start the server
in daemon mode any more.  This is fixed now.  It remains a question whether
mserver should be able to cope with a closed stdin, or not (like it does
now, and just reads whatever currently is opened on filedescriptor 0).
