When an error occurs in calling a function in `window-scroll-functions'
Emacs may behave very strangely. With Emacs -Q inserting
(defun foo (window start)
(error "?"))
(add-hook 'window-scroll-functions 'foo nil t)
in *scratch*, doing M-x `eval-buffer', and then C-l, Emacs shows me the
window without scrollbar, modeline, and buffer text.
In GNU Emacs 22.0.50.1 (i386-mingw-windows98.3000)
of 2006-08-27 on MACHNO
X server distributor `Microsoft Corp.', version 4.90.3000
configured using `configure --with-gcc (3.4)'
BTW, Emacs 21.2 shows scrollbar, modeline, and buffer text for this.

I don't think it is a requirement to fix this. To fix it would be an
improvement, so it would be nice to install a safe fix if someone can
find one. But if we don't find a safe fix, I would rather make no
change.
Perhaps just using safe_run_hooks or something similar
will do the job.
