I'd be happy with a solution like this but can't see how it would work
for me. How could $WINDOW ever be set at initial login? Maybe, in your
case, you're using a command line ssh client which carries $WINDOW
with it? In my case each new login is from a Windows box using Putty
so nothing is the child of anything else from the initiating side.
