Pages in the cluster are mmaped via the nopage method as decribed in
Linux Device Drivers : http://www.xml.com/ldd/chapter/book/ch13.html#t2
in section "Remapping RAM". When the userspace program writes on a page,
it gets the dirty bit.

   I'm unclean, a libertine, every time you vent your spleen, I seem to lose
    the power of speech, you're slipping slowly from my reach, you grow me
        like an evergreen, you've never seen me lonely at all. (Placebo)
