Of course. We agree. This particular problem doesn't have a solution
yet, but if someone has ideas, feel free to describe them and submit
patches.

Please file bugs for those, with recipes to reproduce the slowness,
and I assure you they will be looked at.

I agree. The issue is how to solve those problems, not whether we
want to or should.

The particular issue with long lines doesn't need any test suite to
reveal it. It's a known issue, ever since Emacs 21.1 was developed;
it's not a regression that somehow slipped into Emacs. I filed bug
#13675 for it to make a statement: we don't want to live with this
problem, we want to solve it. Ideas for how are welcome.
Thanks.
