Sure :)

The question is what we would gain, ie how the cache hit/miss ratio 
develops, but I will give it a try.

Personally, I think the outcome won't be too different or even worse 
from what I observered with the anonymous page cache: The pages will be 
invalidated too soon to get hit a second time. But maybe I am wrong.
