When creating a mock object for `process`, `process.send` is just referenced from the parent context, which means that a test has access to the real IPC channel established by `jest-worker`, thus breaking the sandbox. As per the Node definition, `process.send` is not defined if the Node process hasn't started off a `fork` call; but this shouldn't be an issue because `send` has always been exposed and no one complained so far 🙃

Any other functions on it while we're here?

I've thought about it and I don't think so. Maybe newProcess.exit, but I thougth it was better to let it exit.

Might be cool to log a "process.exit() called from test" or something, potentially with a stack. Rarely on purpose, is it?
