  # Does a strict host verification, looking the server up in the known
  # host files to see if a key has already been seen for this server. If this
  # server does not appear in any host file, this will silently add the
  # server. If the server does appear at least once, but the key given does
  # not match any known for the server, an exception will be raised (HostKeyMismatch).
  # Otherwise, this returns true.
