Although I will add that not caching highly useful inner pages for the
medium term, because that index isn't being used at all for 5 minutes
probably is very bad. Using the 4,828 buffers that it would take to
store all the inner pages (as in my large primary index example) to go
store something else is probably penny wise and pound foolish.
