Log:    expose rlib.rtimer.read_timestamp as __pypy__.debug_read_timestamp.
        The underlying idea is that these values are now exposed to applevel
        by gchooks (in particular, stats.duration), so some 3rd-party
        library might want to use this to do calibration or to convert the
        raw values to (milli)seconds
