So time at the start, not the flush_count/getpid. Maybe I'm missing something, but couldn't we just re-use the trace2 SID + a more trivial trailer? It would have the nice property that you could find the trace2 SID whenever you looked at such a token (could e.g. split them by "/" too), and add the tv_usec, flush_count+whatever else is needed to make it unique after the "/", no?
