> `window-state-put' as used within the following functions does not work.

> Steps to reproduce:
> 1) Start via `emacs -Q'.
> 2) evaluate the two functions:
> (defun my-save-frame ()
>   (interactive)
>   (let ((buf (find-file-noselect "/tmp/emacs-layout")))
>     (set-buffer buf)
>     (erase-buffer)

>     (set-buffer buf)
>     (beginning-of-buffer)
>     (window-state-put (read buf))
>     (kill-buffer)))
