I don't see it when running the test on its own, but if large tests are
executed with enough parallelism, the above failure shows up. I didn't see it
before this change, but I can't say for certain. I'm sorry, I wish I could be
more definitive. I'm running the test in a loop 100 times to see if it will
flake on its own even if it's the only thing on the CPU at the time.
