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.
