Another option, when there is a limit on M pages to return, might be to
-cull the M top pages without sorting the rest. This could be done using
-a variant of Ye Olde Bubble Sort. Take the first M pages, and (quick)sort.
-Then for each of the rest, check if it is higher than the Mth page.
-If it is, bubble it up so it's sorted.
-If not, throw it out (that's the fast bit and why this is not O(N^2)).
