The cleanup loop did not manage those situations well when a connection failed or
the connection success but the code did not add a peer connection to it yet.
- in the cleanup loop check if a connection failed to a server
- after adding a foreign server connection force to keep it a minimum 5 sec
* Exit from processConnResults after all tries
If all server is unavailable then the server picker never return
because we never close the result channel.
Count the number of the results and exit when we reached the
expected size
