   This test is really testing a pathological case ... when the vectors are all the same everything is equidistant from everything else and "nearest neighbor" ceases to really even mean anything. I'm not sure we should actually have this test other than to verify that there is no crash. Maybe I'm misunderstanding, but what it the test really asserting?
