  2.1.7 is more aggressive about failing requests from one server to
another when a home server goes down.  See "no_response_fail" in proxy.conf.

  It's also more aggressive about *not* using zombie servers.  It treats
zombie servers as dead for new requests.  i.e. it will retransmit the
*same* request to a zombie server, but a *new* request will ignore the
zombie server.

  That change was really made for stability.  If a home server isn't
responding, we shouldn't really be sending it new packets.  Yes, this
might break EAP.  But if the home server isn't responding, it's not
doing EAP already, right?
