Loading saved window arrangements from a client's configuration file is 
the likely reason. At the moment this is a problem for migrating our 
software to Wayland. I understand the desire to remove this from Wayland 
but I am somewhat stumped on any other way for Wayland to provide this 
functionality. It appears it is possible for X clients to do this, so I 
think the battle is lost and Wayland should add this for non-X clients.

I agree the supplied code should not work. Attempting to set a loop in 
the surface parents should be an error.
