When the same buffer appears in more than one window the `walk-windows'
in `linum-configuration-change' together with

        (mapc #'linum-update-window
              (get-buffer-window-list linum-buffer nil 'visible)))

seems to update line numbers twice when the same buffer is displayed in
more than one window.  Why do you want to update numbers on any but the
selected frame here?  Also, after scrolling it should be sufficient to
consider the scrolled window only.  The `string-match' in
`linum-after-change' should become `string-match-p' to avoid clobbering
match data.
