" ... but Object Cache would allow us to stuff the results of the selector into a cache, so we wouldn't have to grab them from the DOM again."

You are not 'stuffing' anything anuwhere else but in the array of the cache. And most importantly, you are stuffing references to dom nodes. Same as jQery does.

It is therefore of no use to reuse the $listitems (as above) because anything can happen to the actual dom nodes being referenced. they can also be removed. all of them or just some.

And another jQ instance which is just the reference to the original one, will happily proceed working on removed nodes, for a while. untill erros start flying arround.

Therefore: do not cache and do not reuse REFERENCES.
Because actual objects can change or dissapear.
