Yes, I wanted to have all the credit to my name! All mine!

Seriously, I didn't mean to imply that you did anything improper, and I'm genuinely pleased that we ended up with a good solution.

This business makes me wonder if there are more cases where the linear marker list causes bad performance. Probably not very often but it's not unreasonable for a mode to have many data structures with many (live) markers into the text, and that would lead to text changes going from O(1) to O(text size). In any case, not anything to worry about right now.
