Actually, those don't do much. The longer tris just get smaller, but still very very skinny. You have to zoom WAY in to see that they have any thickness at all. There needs to be some kind of 'annealing' feature that takes skinny triangles and collapses them down in some fashion. This is probably most important along the trim curves, where a lot of skinny tris can be created.

It's a minor gotcha. The meshes are already pretty clean.

Hi Crusoe, well even though it is minor I'd like to check it out and see if I can tweak things to make it better...

Can you possibly send me the model? Just the surfaces that have the long skinnys and possibly the adjacent pieces to those surfaces. If you'd like to keep it private you can e-mail it to me at moi@moi3d.com

There is already some stuff in place that tries to avoid creating long skinny triangles during the triangulation phase, but if I have some examples where long skinnys are being generated I might be able to tune that up a bit to make that work better.
