We don't do anything with it, probably because the frame was already
resized.

IOW, we don't wait with a resize until we get a notification, but
instead resize the frame itself, and then might resize again when we
receive WM_SIZE. Question: why not wait for WM_SIZE, and only resize
after it arrives? That would emulate better what X does, and also
prevent the second resize. No?

I don't remember saying that (and don't know X well enough to make
such assertions to begin with), but in any case, you just explained
that I was wrong, and there is a Windows message equivalent to
ConfigureNotify.
