Program to dirty memory in a controlled way

[SunnyRaj]

Simple program that reserves a bunch of memory (may be use malloc), and dirties it. Possibly just a ~10 line program. The goal is dirty the pages at a controlled rate. The input can be how many pages to dirty and at what rate(how many pages to dirty per unit time). May be an output of how many it dirtied for the time the program ran.

this may not be worth the effort to write ourselves. The parsec benchmarks should give us something similar to this since some of them should be more memory intensive than others.

PARSEC is already a todo list in #11.
