Nice one, @MartijnRas !
Creative way to do that! :)

plus, you could add to the _conf structure, a null property called PPWSrc.
Then, in the end of the _createPPWSrcPath you set the path to _conf.PPWSrc.
In the first line of _createPPWSrcPath, you verify if you already have the _conf.PPWSrc defined or if it is null...if it is already there, then just return it, avoiding breaking the URL and looping through the scripts...what do you think?
This would make the whole block of code just run once, just returning it cached when called again.
