Try attached patch. > <top.diff> I'm a long term top user and it used to work. For example, when I was running head -r340287 it worked as I remember. (I recreated such a vintage recently for a test of something else. The -opid ordering was coherent as I remember, unlike the above.) It historically seemed to track the time order of process creation, even around the PID number wrapping around. (So not a strict PID sort, at least for the PID shown.) This was handy for monitoring buildworld buidkernel and port builds (all parallel). I'll probably try the patch when I have a chance, even if it does strict PID number order.
