Just to clarify - rather than necessarily finish in a specific order, the tasks must not finish before one (or, in the general case, one or more) other task is finished. You have queried my use of fork, but are you really saying that fork is only appropriate where the tasks are entirely independent? As an illustration, in the websale example, is it not reasonable to assume that 'ship item' should not complete before 'wait for money' was completed? Now while the join perhaps implies this synchronisation, the 'ship item' node can fully complete even if 'wait for money' never completes...
