> As a first step to introduce a mailbox model, we need to split up the monolithic loops in stream task implementations into stepwise actions. The step-wise actions are still run in a loop, but give us the opportunity to check the mailbox between each step in the future. This mailbox will be added to the loop in a later subtasks.
> We also exclude breaking the stream sources into steps because this is not possible before FLIP-27 is implemented and we need to be compatible to the current source function interface.
