We don't really need 2GB of leakage to find the problem ... a query
that generates a couple hundred meg of bloat would be plenty.

Since we don't know how much space the query would have needed to run to
completion, it's likely that something involving much less than a tenth
as much data would still be enough to make the leak obvious.
