Raspberry PI node EventEmitter memory leak

I'm using the johnny-five node module on a Raspberry PI to drive a few servos on a robot with the following script

var five = require('johnny-five'), board, servo, led;

board = new five.Board();

board.on('ready', function(){
        servo = new five.Servo({pin: 9, range:[0,180]});

        // Allow direct commandline access
        board.repl.inject({s: servo});
});

I get the following error when running this code on the Raspberry PI with node 0.10.29-1

 1(node) warning: possible EventEmitter memory leak detected. 11 listeners added. Use emitter.setMaxListeners() to increase limit.

 Need to setMaxListeners somewhere in the code.

If however I run this code on my notebook (Linux Mint 14 + node 0.10.20) it works fine.

Is there a way to setMaxListeners globally on the Raspberry PI (running raspbian)?

If not, how would I add setMaxListeners to my code?
