You're solving the "here is a selector, find the nodes it matches" problem. The "fast" profile is meant to solve the "here is a node, find all the selectors that match it" problem, since the latter problem is the one relevant to CSS styling of a DOM. I suggest you think carefully about how you would implement the "id selector only matches the first node in the DOM with that id" behavior in the "here is a node, find all the selectors that match it" problem. -Boris
