Thanks for pointing this out. I'll have a more detailed look when I get
a minute, but we do have some known issues around parallelism: if
multiple messages are being parsed at the same time, we can end up
getting things wrong, and this happens from time to time on
OzLabs. That's probably what went wrong... although it is weird for it
to happen to multiple revisions of the same series... anyway as I say
I'll take a look when I get a chance.

... and we do have code to do this, which is what makes me a bit
suspicious that you've just lost a race.
