I think he might mean that invalidating the cache of a large number of semi-popular long tail pages (being the long numper pages we serve less hits to, but hit a similar volume of traffic to a page like MW's when you add all of them together) at the same time could create a similar performance issue to the invalidation of a single extremely article article like MJ was. Simply because we're invalidating a number of not top-## pages, but popular enough that the total number of people viewing the collection of pages gets close to the traffic one MJ-popular article gets.
Sorry, you folks get used to communication via IRC, and then use IRC'ish internal speak.... Anyway, I remember the MJ day, and went back and read that thread.
Whatever happened to Domas' idea that, for things already in the cache and about to be invalidated, a newly parsed instance be stored in memcache before invalidating other caches, so that the article is only parsed once?
