And if by "weird" you mean "flock is really not a well-defined or sane
interface", I'll agree with you.

That said, I'm not at all sure about the "we're stuck with it". We can
improve the semantics without anybody noticing, because it's not like
anybody could *depend* on the weaker semantics - they needed
particular races and timings to hit anyway.
