In Emacs 22, buffer point behaved as if it were frame-local: at step 9, point would still be at (point-min). This change may seem innocuous, but it can be quite frustrating and mysterious if you have a multi-tty frame open at another site. The buffer point behaves as if it's "stuck": every time you switch away from the buffer and return, the point has returned to its sticky position. The behavior exhibits in both multi-tty and single-tty flavors, but is easier to trigger in a long-running multi-tty session distributed over multiple sites (e.g. home and work).
