patch

Old code seems to have "cleverly" avoided a source of n^2 algorithm cost, by computing as we descend the tree. New code walks the parent list so is potentially slower for very deep trees. Makes me wonder if we should have some kind of stress test for a deeply nested tree. I’m sure many of our algorithms have such issues, not sure what our performance/scaling goals are for them.
