Ben, with the proxy logic does this work for min_retry_delay? If we bypass on
the non-alt proxies, then we will never check the alt proxies and see if the
delay is smaller. I know the previous method just looked at all proxies in the
retry map and found the minimum, so I was wondering if that was necessary to do
here.
