9 because I haven't found a way to run it myself.
11 However, I constructed a benchmark which shows at least one possible slow point.
12 The HTML5 spec talks about creating a new document for every time we use
13 the fragment parsing algorithm. Document() it turns out, it a huge bloated
14 mess, and the constructor and destructor do a huge amount of work.
