Comment (by zooko):

 Okay I think I understand the bug now.
 [source:trunk/src/allmydata/immutable/downloader/finder.py at 4707#L217
 ShareFinder._deliver_shares()] calls
 {{{eventually(self.share_consumer.got_shares, shares)}}} and then in the
 next tick—''before'' {{{got_shares()}}} has been
 executed—[source:trunk/src/allmydata/immutable/downloader/finder.py at 4707#L89
 ShareFinder.loop()] runs and gives up and aborts the download because it
 isn't aware of the shares that were going to be delivered to it in a
 subsequent tick.
