Try looking at the 'xprop' (and similar, xwd, etc.) source, how they find a
top-level window (with or without the frame) when you click on any subwindow.

You also need to think of any kind of application that opens several
top-level windows, and don't know how to decide which one to put the property
in. You might want to take a look at xlsclients(1) - this might be a good
way to find top-level windows for any clients conforming to the session-
management standards.

If you want, you can also have a root-window property on the root window,
containing text defining the rl property by process, rather than by window
(e.g., each process is defined by a (hostname,pid) pair).
