The relative_pid is always 1. In mworker mode we also have a child->relative_pid which is always equalt relative_pid, except for a master (0) or external process (-1), but these types are usually tested for, except for one place that was amended to carefully check for the PROC_O_TYPE_WORKER option. Changes were pretty limited as most usages of relative_pid were for designating a process in stats output and peers protocol.
