The network flow is something like:

at the start call try_outbound_connects() which does a for loop calling
try_connect_once() N times.

1. try_connect_once()
hosts.fetch_address()
2. attempt_connect()
FAIL: try_connect_once()
connect()
3. handle_connect()
FAIL: try_connect_once()
setup_new_channel() / subscribe_stop()
4. channel_stopped()
try_connect_once()

so I'm not sure where it is creating +1 connections. there should be N
slots that are always reconnecting and that's it. but for some reason it
manages to get past 8 to 9 connection attempts.
