The copies do not interact. Native-addons do not see modifications to `process.env` from Worker threads, but child processes started from Workers do default to the Worker’s copy of `process.env`. This makes Workers behave like child processes as far as `process.env` is concerned, and an option corresponding to the `child_process` module’s `env` option is added to the constructor.
