We normally try to catch these sorts of things with regression tests.
Of course, that requires having a test that would catch a particular
problem, which we don't seem to have for this particular case. A
performance test would also require testing a particular scenario, so
I don't see why that's better. A regression test is better suited as
there's no middle ground between pass and fail.
