------- Comment #2 from opendarwin.org at mitzpettel.com  2006-09-09 00:40 PDT -------
Most of the time is spent in one call to VisiblePosition::canonicalPosition(),
and under that in one call to each of Position::upstream(),
Position::downstream(), nextCandidate() and previousCandidate(). The position
to canonicalize is sitting in a very wide tree of unrendered content. The above
4 calls are O(n^2) since they essentially loop using Position::next() which in
turn half the time uses Node::nodeIndex() which is O(n).
