If you do (setq long-line-threshold nil), M-> is fast. Only when you
omit it does Emacs hang. Hmm. It's meant to be the other way around,
isn't it? ;-)

What isn't so clever is that with a long line of y's, C-p, C-n, M-v, C-v
are slower than inserting the long line. The profiler on M-v indicated
that scroll-down-command was taking 86% of the time.
