That almost works. I've certainly got a structure that I can use to
reset the frame configuration manually now. However if I call it in the
new frame handler:

(defun crmbk-new-frame-handler (frame)
  "Do any appropriate set-up on new frame creation.
This is intended to be called during after-make-frame-functions"
  (when (frame-parameter frame 'display)
    (set-frame-parameter frame 'fullscreen 'fullboth)
    (setq crmbk-current-frame frame)
    (when crmbk-previous-frame-config
      (window-state-put crmbk-previous-frame-config))
    (crmbk-frame-mode t)))

The new frame hangs until I C-g at which point *Messages* reads:

window-state-put: Window #<window 1 on *scratch*> too small to accommodate state
Quit
Error in post-command-hook (winner-save-old-configurations): (error "Window is 
on a different frame")

Should I restore the frame configuration on a later hook?
