I was thinking that if we know that the peer doesn't want the article, we
should stop sending it, but the more I think about it, the more I realize
that's a stupid idea since then we're sending a corrupted message and if
for some reason the peer actually keeps it, we really screwed up.  Not to
mention that doing that is going to be rather hard, given innfeed's

Oh, I see.  Because the network sending routines don't have any idea
they're sending articles, just that they're sending buffers, and teaching
them about the articles is pointless complexity.

You're right, your original solution is best, even if we're doing even
more reference counting.
