guess what? i had the same idea ... but i'd also automatically extract
library dependencies from objects.

i think explicitly touching every page is a bad idea, as it it enforces
a certain loading order (you could use MADV_SEQUENTIAL just as well).
instead, only do the mappings and advices (and let the program linger in
the background for some time, in case pending requests are discarded
when the requesting program exits prematurely).
