This got me thinking. The size of the screen is updated when xrandr
rotates the screen. Hence I thought sawfish was handling
the event. I looked today at events.c and found a hook:
'configure-notify-hook that gets executed by the same code that
resets the size of the screen.

So I hooked a function, and yes, it works. This is my current hooked
function (it could be improved to handle
moving the current window inside the boundaries of the screen and to
make sure there is one window to resize.

(Something else I'd like to implement is the ability to keep 2
geometries: one for portrait and one for landscape mode,
similar to the way Maximize keeps the geometry before the maximization).

(defun dmg-after-rotate ()
  (dmg-remaximize-window  (car (window-order current-workspace nil nil)))
  (display-message "This is a test3")

(add-hook 'configure-notify-hook dmg-after-rotate)

;;; this is my remaximize window.
(defun dmg-remaximize-window (w )
  "remaximize the given window"
  (interactive "%W")
        (let* (
               (m  (window-maximized-p w))
               (h  (window-maximized-horizontally-p w))
               (v  (window-maximized-vertically-p w))
	  (if (and m)
		(unmaximize-window w)
		(dmg-move-window-inside w)
		 ((and v h)
		  (maximize-window w)
		  ) ; and v h
		 ((and v)
		  (maximize-window-vertically w)
		  ) ; and v
                 (maximize-window-horizontally w)
                ) ; end cond
            ) ; end progn
            (dmg-move-window-inside w)
	  ) ; end let
