> 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.
