### Threads

#### Application's calling thread

The application-layer must block on writing I/O. We can't return from a write until we've pushed its bytes onto the socket. Otherwise, if the write fails we are unable to deliver its IOException to the application. We would have told the application layer that the write succeeded, but it didn't!

    assertThat(socket.enabledCipherSuites)
      .containsExactly(*expectedCipherSuites.toTypedArray())
  }
