Chunk of data to add. Note that the first event in the chunk must have higher time value for the chunk to be added (false will be returned on error). This can be ensured by emitting a checkpoint event with the Profiler that produces the chunk before any other events in the chunk. Also note that data must not be deallocated for as long as the ChunkyEventList exists; the ChunkyEventList will use data directly instead of creating a copy.
true on success, false if the first event in the chunk didn't occur in time after the last event already in the list.
Add a new chunk of profile data.
