I was just thinking what does an accurate PID actually get you? If you looking at some logs with a PID of 20048, does that mean something to you? It doesn't actually mean much because you can't map that back to anything. If you have the device, and the process is still running then you could look it up ..
So lets say logger was modified to record comm values.. That way you could record the actual process name AND the pid. Well if you use prctl(PR_SET_NAME), you can forge comm values. So that doesn't get you much either..
So even if you record accurate PID values, it doesn't mean anything anyway.
