I thought that's exactly what it does. :)

Edit:
Nevermind, and sorry if I caused any confusion... I was confused a bit myself. I read more about it, and it seems that ASLR does not modify virtual addresses at run-time, only at image load-time (or for the heap, at heap-creation time).

So the wikipedia page seems to be a bit wrong in this case. :)

I mean this: "Entropy is increased by either raising the amount of virtual memory area space over which the randomization occurs or reducing the period over which the randomization occurs. The period is typically implemented as small as possible, so most systems must increase VMA space randomization."

From here: http://en.wikipedia.org/wiki/Address_space_layout_randomization#Effectiveness

It seems to imply that randomization is done at "periods" of time, while the application is running, and that those periods are really small... Hmm. "Period" does not refer to an amount of time in this case, does it? :D
