What kind of use cases do you imagine for category intersection? I suspect that as soon as you open the door to intersections ("hey everyone you can find all the articles that are both 1895 deaths and poets!") then people will want arbitrary numbers of intersections ("hmm, '1895 deaths, poets and unreferenced' didn't work"). Maybe it would be possible, along the lines you suggest, to allow greater numbers of intersections in some time-restricted way ("You requested a 4-level intersection less than a minute ago. Please wait and try again.")
Is it not feasible, for example, to perform all intersections on a different machine or something? I seem to recall someone was operating a 3rd party category intersection site...?
