The problem stems from how Emacs handles lines, basically: Many functions, like font-locking, run from redisplay, and wants to determine the syntax by looking at a line as (more or less) a unit. And that leads to Emacs hanging if the mode’s font-lock rules hasn’t been written in a careful manner, and they mostly haven’t. From the author's latest blog update. So, at last, we're not all going to need tricks in our Emacs init files anymore to make sure Emacs doesn't slow down when files very long lines (as in: thousands of "characters" or more) are opened.
