As I've mentioned in personal discussion I can't say I like this. This just introduced additional complexity to the service interface and leaks away implementation details. What happens if the service is dropped before exit is signalled? This is something the user of this interface should not worry about.

Is this really necessary? There's no event loop blocked on the network anymore.

it's also nice to make sure the network is started before we begin the consensus process.

not needed fro this PR, but in general i'd like to get away from anonymous messages at anything more verbose than the info! level. enabling debug and trace is a currently a mess, so doesn't really make sense to enable them without specifying a target filter.

You can always filter by module. I usually use an explicit target to logically group logs coming from several modules under a single filter. If there is just a single module there's no need for that.
