Well, really this is iteration via a combination of iteration and
recursion :-). Overall, the code iterates over a list of groups; the
list is the set of groups reachable by reference from some initial

But you're right: we could use a subpool for the for-loop, and then
the pool growth would be bound by just the depth of the recursion.
