"A good driver sometimes misses a turn, a bad driver never misses a turn"

A good engineer knows that all real-time systems are turn-based, and the network is _always_ partitioned

This is exactly the right way to think about it. One should be happy when the network works, and not expect any packet to make it somewhere on any particular schedule. Ideally. In practice it's too expensive to plan this way for most systems, so we compensate by pretending the failure modes don't exist.
