  **Old English à la Beowulf**
  ```
  Banman wæs bréme    --blaéd wíde sprang--
  Connmanes eafera    Coreum in.
  aéglaéca            léodum forstandan
  Swá bealdode        bearn Connmanes
  guma gúðum cúð      gódum daédum·
  dréah æfter dóme·   nealles druncne slóg
  ```

  **Modern English Translation**
  ```
  Banman was famed              --his renown spread wide--
  Conman's hier,                in Core-land.
  against the evil creature     defend the people
  Thus he was bold,             the son of Connman
  man famed in war,             for good deeds;
  he led his life for glory,    never, having drunk, slew
  ```

  With @theuni's blessing, here is Banman, rebased. Original PR: https://github.com/bitcoin/bitcoin/pull/11457

  Followup PRs:
  1. Give `CNode` a `Disconnect` method ([source](https://github.com/bitcoin/bitcoin/pull/14605#discussion_r248065847))
  2. Add a comment to `std::atomic_bool fDisconnect` in `net.h` that setting this to true will cause the node to be disconnected the next time `DisconnectNodes()` runs ([source](https://github.com/bitcoin/bitcoin/pull/14605#discussion_r248384309))
