With linum.el version 0.9u+ (the latest version as of this posting),
Emacs 22.1 does not show the display bug.  When I posted, I had tested
with linum.el version 0.9t, which does show the bug.  For the record,
here is the recipe:

1. Save the following lines  ~/linum-test.el:

(load-file "<path/to/linum.el>") ;; linum.el version 0.9t
(setq linum-format
      (lambda (line)
        (propertize (format "%d" line) 'face 'linum)))
(setq confirm-kill-emacs 'y-or-n-p)

2. emacs -q -l ~/linum-test.el ;; Emacs 22.1

3. M-x display-splash-screen

4. M-x linum-mode

5. C-x C-c

Now the display bug is seen.

Unlike Emacs 22.1, my current CVS Emacs (from the trunk) shows the bug
also with the current linum.el version 0.9u+ (GNU Emacs 23.0.50.1
(i686-pc-linux-gnu, GTK+ Version 2.10.6) of 2007-09-23).
