Particle.process() Not Supported

First reported here: https://neighborhood.bluz.io/t/micro-epaper-for-bluz/800

Particle.process() does not process cloud data. So the following will hang bluz and prevent it from connecting:

void loop() {
    while (true) {
        Particle.process();
    }
}

Particle.process() should allow the user to block the main CPU if necessary but still process cloud data and have the RGB LED updated.
