Yes, that would be basically a set-window-configuration.
Another approach is to have a transactional interface, like
start-window-configuration and end-window-configuration:
- during the transaction, windows can be resized to too-large/too-small
sizes (but maybe window-fixed-size should stil be obeyed?).
- if redisplay happens inbetween, it's an error, and the resulting display
will be blank.

If you let my code run longer, you'll see that it often cycles between
a few different configurations, but as far as I've been able to tell,
those are very similar: it's just a matter of off-by-one
issues, usually. Still, there are corner cases where it oscillates
a lot more. This is why I put an upper bound rather than "loop until it
settles".
