Yeah, I think we've established that having some way to force that,
without using a huge test case, would be really desirable. Maybe
just provide a way to put an artificial limit on how many tuples
processed per pass?
(And no, I wasn't trying to rag on Melanie. My point here is that
we've failed to design-in easy testability of this code path, and
that's surely not her fault.)
