    and update_wall_time_one_tick misses out on this bit:

    /* Reduce by this step the amount of time left */
    time_adjust -= time_adjust_step;

    That's why I said that update_wall_time_one_tick needs both
    time_adjust_step and delta_nsec. If you have a nice way to return
    both values, please let me know...
