Since it doesn’t seem to have completely blown up in your face, I can assume that I was on basically the right track, and do a bit more refinement on the peeling code.  There probably is some room for efficiency improvements.

If I do some pre-computation at shaper configuration time, I think I can efficiently handle the cases you mention.
