,StatsEventHandlerImpl
Gather statistics on the times reported to this TimerEventHandler. It will keep
events from different thread separated in order to get good results, but the
result of the stats call merges all of the results together.
The time is the duration between an enter and an exit call to a timer from the same thread. Recursive calls are matched, and the results accumulated as in any other case.
