> This is one of the causes of unstable integration tests.
> When a worker starts, WorkerState boots up a Server, which binds Netty to a
> port in order to receive messages from other workers. Slightly later, we
> register a callback with the server that defines where the Server should
> deliver received messages.
> In the interim between binding the port and registering the callbacks, Storm
> quietly discards any received messages.
> Other workers will happily send messages to the worker that is not ready, as
> the sending side considers an open connection to be sufficient to send
> messages.
> We should change the setup so we set the receive callback before we start the
> Server.
