This is fine.

Code like this (and other parts of this file) makes me
think that this loop could be peeled via a template parameter on
the function (or lt object), and structure the code for this function as
a stable/notstable specializations (ie, stable policy). (or as
stable/non-stable specializations of LT.)

Just a thought.

It would probably be a lot cleaner.
