We don't have a way to make the isolation tests change behavior depending
on how the backend is compiled. So the only actually available fix is to
make that test take "a minute or more" for *everybody*.

Aside from that, it's just disturbing that these tests aren't
deterministic regardless of machine speed. We don't seem to have a
way around that right now, but I wish we did.
