Use for the parallel flow continuation point.
All parallel flow instances are equivalent and connected to the same Begin or Next events that happened previously. An example of a flow start point is job scheduling. For instance, IJobParallelForExtensions.Schedule generates an implicit Begin Profiler flow event and IJobParallelFor.Execute generates an implicit ParallelNext event.
