[ thinks about it a bit more... ] Actually, maybe it doesn't. The thing
that made 9f03ca915196dfc8 really nasty is that it built an index that was
actually corrupt, with incorrect hash codes stored for entries. I think
your assertion would probably have caught that, but only accidentally,
because the problem had little to do with whether the sort satisfied its
charter. Maybe we should stick at least one simple test query in there
before we drop the index again.
