apetushkov@9858	34	*
apetushkov@9858	35	* If a traceid is used, depending on epoch, either the first or the second bit is tagged.
apetushkov@9858	36	* If a class member (method) is used, either the third or fourth bit is tagged.
apetushkov@9858	37	* Which bit to set is a function of the epoch. This allows for concurrent tagging.
apetushkov@9858	38	*
apetushkov@9858	39	* LeakProfiler subsystem gets its own byte and uses the same tagging scheme but is shifted up 8.
apetushkov@9858	40	*
apetushkov@9858	41	* We also tag the individual method by using the TraceFlag field,
