Yeah, so the backports version of `Random.srand` did not actually invoke `Kernel.srand`, which is pretty important if we use `RSpec::Core::Random.srand`. Of course, we could forego that and just call Kernel.srand directly, but I would prefer to wrap it up somewhere. For now, that's by having a single call to `RSpec::Core::Random.srand` (again, the refactor I would like to do later would clean this up a bit, too).
