intermittent unit test failure

[gregcaporaso]

I just ran the test suite and got the failure below. I re-ran the test suite, and didn't get it again, so I think maybe this is an intermittent test failure resulting to the non-deterministic underlying functionality. Not urgent, but if we can make this a really low frequency occurrence that will be convenient, but at the very least it's documented here.

Ok, just got it again, so maybe this isn't very uncommon.
