Result.

kernel Object
(
    [processes] => Array
        (
            [0] => init Object
                (
                    [processes] => Array
                        (
                            [0] => getty Object
                                (
                                    [processes] => Array
                                        (
                                            [0] => login Object
                                                (
                                                    [stdin] => Resource id #8
                                                    [processes] => 
                                                )

                                        )

                                )

                        )

                )

        )

)


Expected!
