Si estás utilizando libraries de terceros que te dicen que las llames con `await`, del tipo:

```Python
results = await some_library()
```

            waiting.countDown()
            result = daemonConnection.receive(20, TimeUnit.SECONDS)
            received.countDown()
        }
        waiting.await()
        Thread.sleep(500)
        connection.queueIncoming("incoming")
        received.await()

        then:
        result instanceof Received
        result.message == "incoming"
    }

    def "receive blocks until connection stopped"() {

    }

    @Override
    public void await() throws InterruptedException {
      lock.lock();
      try {
        condition.await();
      } finally {
        lock.unlock();
      }
    }

    @Override
    public boolean await(long time, TimeUnit unit) throws InterruptedException {
      lock.lock();
      try {
        return condition.await(time, unit);
      } finally {
