A value of 0 means unlimited.
``dht_upload_rate_limit`` sets the rate limit on the DHT. This is specified in
bytes per second and defaults to 4000. For busy boxes with lots of torrents
that requires more DHT traffic, this should be raised.
``unchoke_slots_limit`` is the mac number of unchoked peers in the session.
The number of unchoke slots may be ignored depending on what
