I don't think cache is worthy, as I have wrote few days ago considering the brilliant strategy used by NWMatcher: http://webreflection.blogspot.com/2009/10/nwmatcher-quick-look.html
In few words, we use jQuery to constantly manipulate the DOM, common tests with the same selector repeated 100 times do not make sense in real case scenarios. It's like creating a static HTML page for one of those pages that keep constantly changing, a wast of resources/time (speed) rather than performances boost ... and for this reason considered a bad practice. Diego strategy is probably something Sizzle should implement at some point, not much for the DOM part and mutation events, but for specific pre-compiled functions. Just my opinion.
