>
> TestRandomRequestDistribution.testRequestTracking() is a badly written test
> that tries to assert that if 10 requests are sent to a shard has 2 replicas,
> at least 1 of those requests must be routed to each replica.
> This is essentially a test that says "flip a coin 10 times, fail if all 10
> are heads *OR* if all 10 are tails"
> Statistically speaking 2 out of every 1024 runs of this test (1/512) should
> fail.
