More specifically it extends the work that was done for per thread scenarios to handle more than a single trace ID. It also temporally correlate traces based on timestamp generated by the tracers so that rendering by the perf mechanic is ordered. Everything is based on Arnaldo's perf/core branch (46d4c9a05285). I will send another revision when it is rebased to a 5.2 rc candidate.
