It's an unlikely scenario and I might be paranoid, but what if the tests
were running on a cluster under heavy traffic? For instance, what if the tests
were to be run on OpenStack, and the test just happened to run when there is
unrelated heavy traffic (say, Hadoop shuffle) pressuring the switches?
