Where does 'window' come from?  At the time 'buffer-list-update-hook'
gets called, there's no guarantee that the buffer whose local hook
runs is even shown in a window.

It's the right buffer at the time you run this hook.  I'm afraid that
whatever we do here it will get us in a mess that strikes back sooner
or later.  Maybe we really should run a 'select-window-hook' instead.
