Oh, right. I forget that using (usually) one buffer per frame is still uncommon.

See my other mail about that, substituting class/set of buffers for class/set of
frames.

(I obviously don't care much about the blink cursor case. The important use
cases I have are for things like menu-bar and tool-bar, which one typically
doesn't want to suddenly appear in each of the tiny thumbnail frames just
because you turned on menu-bar-mode after it was off.)
