Thanks, but I'm not sure that's gonna work, it seems the API has changed and `Parallel` is now [a module](https://github.com/seattlerb/minitest/commit/34760e3b268bc1bb4ac5fe1a44ef1ff0a2f9bd4d#diff-e0e4e1ef3104bc3b535079c5a5189509R2). Maybe we should make use of the [parallelize_me!](https://github.com/seattlerb/minitest/commit/34760e3b268bc1bb4ac5fe1a44ef1ff0a2f9bd4d#diff-444fa8babd8886c012733b064d709db5R51) method, not sure.
