Hello Daniel, should we have this `maxUnexpected` at all? Perhaps, we keep accepting and ignoring connections/requests that don't match our expectations? The reason I ask this is, I don't think we will know the exact number of unexpected requests/connections that this server might receive when this test is going on, so with this value of 2, I guess there still would be a chance that this test fails because of those unexpected connections?
