I installed a fix to make it faster -- but I can still create
a file which takes minutes to display -- it just requires a line
which is veeeeeeerrrrrryyyyy long.
In my case, that specific .gif file still takes 4-5 seconds to display
even with my fix.
So the fundamental problem of redisplay being O(n) to the length
of lines in the buffer is not fixed, and I don't know how to
solve it (and we certainly shouldn't do this BTR).

Yes, that is a different problem as such -- but I guess we can
find other cases where some activity is stalling redisplay when
redisplay-dont-pause is nil. So I would still like to put some
upper limit on the time where we force a redisplay to actually
update the screen.

That is a work-around for one manifestation of the problem...
