That wouldn't work (or at least it might not do what you expect): once a
too long line has been found in the buffer the long line optimizations are
enabled, and long lines are not detected anymore.

Okay, so my guess is that it's in fact something in the Org fontification
code which infloops when locked narrowing is enabled.
