if interrupted with CTRL+C blocking socket calls will return with -1. Each device should call FairMQDevice::Shutdown() before ending the running state to close open sockets, otherwise the interrupt call itself will block. - FIX: Update number of received messages for FairMQFileSink. - Add ability to poll on outputs for FairMQPoller.
