      1. start a new cluster with 3 config servers and one shard
      2. create a new sharded collection
      3. do some finds - all are fast (less than a second)
      4. block the first config server with iptables --DROP
      5. create a new connection
      6. try finds on the new and the existing connections - all are fast
      7. try inserts on the new and the existing connections - all are 5s

      Test-case in python is attached (uses my own mongo-docker framework). LogLevel 5 logs too.
