When pop-to-buffer finds itself in a tight spot (no space on current frame),
I think it will/would in certain situations pop a new frame.

I have a vague recollection that the recipe was accurate, and eventually
something in window.el was fixed, by me or Martin or both.  Likely I
forgot to x-ref the bug id.  If you can't reproduce it, I think you should
just close this bug.

Hey, I found commit 5d34e1b2881caa5743816030c2e9cdcda58e9719
that looks relevant.
