Comment 11 for bug 487313

review+ from me too, but two queries before we merge given that we obviously end up querying the same streamhost repeatedly:
1. What happens when this has happened >5 times? Do we discard the oldest 6th, or do we end up with an ever-growing list of streamhosts?
2. In the likely case our server has remained connected to the same proxy, do we remove duplicates from the answers, or do we possibly end up sending the same stream host 5 times in a S5B initiation?
