A RealTimeActor presents the same interface as a JustInTimeActor but doesn't defer work.
Time added will be performed immediately.
Its primary purpose is to allow consumers to remain flexible in their scheduling.

A AsyncJustInTimeActor acts like a JustInTimeActor but additionally contains an AsyncTaskQueue.
