Probably an extreme edge-case, but, it might be good to alias out hasOwnProperty to a var instead of it relying it being available on `module.exports`.

`util-common-js.js`:
```
module.setExports({
  'forEach': function() {}
});
//... several lines later ...
module.setExports({
  'hasOwnProperty': function() { console.log('kaboom'); }
});
```
