I could reproduce the infinite loop in try_scrolling even with the X11
build, on both trunk and the emacs-23 branch.  C-g does not help.

1. emacs -Q
2. Evaluate the following expression in *scratch* with C-x C-e.
     (setq scroll-conservatively 100)
     (setq scroll-preserve-screen-position 'always)
     (goto-char (point-min))
     (set-window-vscroll nil 1 t))
