//! let runtime = tokio::runtime::Runtime::new().unwrap();
//! let (tx1, rx1) = tokio::sync::oneshot::channel::<SocketAddr>();
//! let (tx2, rx2) = tokio::sync::oneshot::channel::<SocketAddr>();

//! runtime.spawn(async move {

//!     tx1.send(ep.local_addr().unwrap()).unwrap();
//!     let addr2 = rx2.await.unwrap();
//!
