495 When blocks terminate (either COMPLETE or CORRUPT/DEAD/BADSEGNUM), the
496 _shares_from_server dict was being popped incorrectly (using shnum as the
497 index instead of serverid). I'm still thinking through the consequences of
498 this bug. It was probably benign and really hard to detect. I think it would
499 cause us to incorrectly believe that we're pulling too many shares from a
500 server, and thus prefer a different server rather than asking for a second
501 share from the first server. The diversity code is intended to spread out the
502 number of shares simultaneously being requested from each server, but with
503 this bug, it might be spreading out the total number of shares requested at
504 all, not just simultaneously. (note that SegmentFetcher is scoped to a single
505 segment, so the effect doesn't last very long).

613  get_servers_for_index -> get_servers_for_psi (now returns IServers)
614 
615 This change still needs to be pushed further down: lots of code is now
616 getting the IServer and then distributing (peerid, rref) internally.
617 Instead, it ought to distribute the IServer internally and delay
