Remarks

A Helper for generic parallel loops, with support for timeslicing. This version only uses indexes allowing more flexible usage to process many arrays in parallel or use it for other batch updating.

Work will be separated in chunks, that will be processed in parallel. Main thread will then collapse incoming data from async tasks. Will use AsyncState.ShouldStop() to stop execution if timeslicing is enabled. Important info:

• We will finish to process and collapse data for all data already in process, even if we need to stop. To mitigate this, try to use small chunk sizes.
• To avoid infinite loops (when we should stop even before starting working), we will at least process 1 chunk of data per thread.
• To have async tasks, you need to have at least 3 available threads (main thread + 2 futures). Otherwise, we will only process on the main thread, without collapse. true if the processing is done, false otherwise. Use this to know if you need to reschedule the task.
