When I started with Position re-writes of yore, Darin Adler raised the concern that every time we return a Posiion object we do a ref-thrash to the underlying node, since we don't have any PassPosition concept.  Obviously PassPosition is a separate patch, but you should be aware, there may be ref-thrash when returning Position objects.
