Yes, I get the same results.

BTW, you can also get this behavior if you (setq scroll-step 1
scroll-conservatively 0) and hold down <down> on a ruler-less regular text
buffer on a slow remote X connection. Once in a while it'll jump a little to
"catch up" to point.

Anyway at least this patch works 95% of the time and never hangs
(is 95% good enough? http://www.jwz.org/doc/worse-is-better.html)
