That works fine until some programmer tells their compiler to
"optimize" for speed and the code porks up due to loop unrolling,
function inlining and such.  Now you can be in a situation where the stuff
is so large its not only blowing the L1, its blowing the L2 as well and
using extra pages.

Having to fault in or swap out an extra page can negate all the nominal
speed gains you may have gotten by producing "book fast" code.
