No this won't work. I don't want *output* in this particular program. I
might want it for others. I just want the typical approach of burying a
buffer once and then having it not surface, even if there's new output.

Just imagine the havoc of *Messages* being a dedicated window and
popping up each time there's a new message, even if you bury it.

I dislike non-soft dedicated windows because they're bad design. I guess
that I could just advice `set-window-dedicated-p' to be a noop in all

If you have 9 minutes and a way to view Youtube videos, you can see my
demo of a neat approach to manipulating windows (especially the window
swap). This approach of course won't work with non-soft dedicated
windows: https://www.youtube.com/watch?v=_qZliI1BKzI.
