The test has this comment: ### simulate race condition with cas As I understand it, it tries to issue two cas updates through different connections with the same cas value more or less in parallel (in a sense that they are not ordered wrt each other), and sees that only one of them succeeds. So it has to get one positive STORED and one negative EXISTS, but it is undefined which connection would win the race. -- Tomash Brechko
