For the debugger it's IMO the best option.

Comparing W2 and W3 per compare-window-configurations would probably
work as a start, but point should probably not be restored.
Here's the code that we use currently:
(defun slime-close-popup-window ()
(when slime-popup-restore-data
(destructuring-bind (popup-window selected-window old-buffer)
slime-popup-restore-data
(bury-buffer)
(when (eq popup-window (selected-window))
(cond ((and (not old-buffer) (not (one-window-p)))
(delete-window popup-window))
((and old-buffer (buffer-live-p old-buffer))
(set-window-buffer popup-window old-buffer))))
(when (window-live-p selected-window)
(select-window selected-window)))
(kill-local-variable 'slime-popup-restore-data)))
popup-window is the window that displays the help content at W2.
selected-window was selected at W1.
old-buffer was the buffer associated with popup-window at W1.
It's far from perfect and it was a PITA to write.
Helmut.
