// both server and client need a connection state object.
// -> server needs it to keep track of multiple connections
// -> client needs it to safely create a new connection state on every new
//    connect in order to avoid data races where a dieing thread might still
//    modify the current state. can't happen if we create a new state each time!
//    (fixes all the flaky tests)
//
// ... besides, it also allows us to share code!
