Greylisting wouldn't explain a delay of more than an hour or so.
OTOH, if B's reply got held for moderation for some reason, then
yeah it could be days :-(. But in that case the rest of the list
didn't see it in real-time either, so having it show up out of
"logical" sequence in the archive doesn't seem like a terrible
reflection of reality. I'm just concerned about the threading not
being sensitive to skews on the order of a few minutes --- those
are extremely common.
