added a native process.nextTick() equivalent - defers execution till next event loop cycle.
Useful for e.g.
sensors.accelerometer.getAcceleration(function (err, data) {
  console.log("2. got the acceleration data");
});
console.log("1. requested acceleration data");

without NodeUtils::Async::NextTick(), the execution order is rather weird.
