I thought about that, too. The argument for the order I chose is that
having start at the start and stop at the end is also intuitive.
But I don't care much and would let the watchdog guys decide what they
prefer.
@Wim+Guenter: Feel free to reorder at application time or ask for a v3
if this v2 doesn't fit your preference.
