IMHO, if a user needs to futz with redisplay-dont-pause to solve her
problems, there's either a bug or a missing feature.  I don't think
redisplay-dont-pause was ever meant for the users, since its effect is
complicated and hard to explain.  In some situations it makes
redisplay more responsive, in others it has the reverse effect.

If redisplay behaves erratically on slow computers, we should handle
that case specially, to avoid the need for playing with
redisplay-dont-pause.
