Having this example https://gist.github.com/mmoreram/6323b9bf536ba5346e5a26117512c208 Have different results when changing the `wyrihaximus/react-child-process-pool` dependency: - Version `1.6.*` work properly in PHP7, composed doesn't update in PHP8 - Version `1.7.*` doesn't work in PHP7 and PHP8 due to compatibility class issues (we already know that issue), - Version `1.8.*` doesn't work in PHP7 nor in PHP8. The `exists()` method keeps waiting until the infinite in both PHP versions. I don't know if some other methods are affected by this update.
