That whole business of using the EState to pass tuplestores back and
forth looks fundamentally broken to me anyway; there's just no way it'll
be certain to link the right nodes together in complicated cases with
multiple recursions. The nodes should be carrying IDs (such as the name
of the WITH item) which they use to search a lookaside list.
