Double loaded helpers?

Hello!

This time, I have only a technical question ;-)

In some cases, it would be nice to use a helper in the constructor of a controller. Like the cookie-helper in my latest case. To do so, I load it. But I also load it in BaseController to use it in other controller.

So my question is: Is the helper in that case double loaded or does CI ignore another try to load it?

The same with model. If I load a mode two times, it it two times in the memory or only once?

That would be such an opportunity to see the code of the framework. 
But the framework is available as a binary. 

OR NOT?

only once.
