I was already reading that page but it doesn't seems to suggest a
solution.

Namely, how to make kill-buffer ask user to save, for buffers that's
not associated with file.

looking at Aquamacs's source... looks like the “solved” it by actually
define its own kill-buffer wrapper, e.g. close-current-window-
asktosave.
