createPage callback not fired in node v0.10

I've noticed that using node 0.10 this code doesn't work

```
(function(){
    var phantom = require('node-phantom');

    phantom.create(function(e, ph){
        ph.createPage(function() {
            console.log("in");
        });
    });
})();
```

not sure what the issue is, but it works just fine with node 0.11 and <0.10
