Here's an example of what I mean:

warcraft scott% wget -q http://cdimages.ubuntu.com/ubuntu-moblin-remix/daily-live/current/karmic-moblin-remix-i386.iso
warcraft scott% md5sum karmic-moblin-remix-i386.iso
91e4f415767a45617f0cbfc5b0abd19c karmic-moblin-remix-i386.iso
warcraft root# sync
warcraft scott% md5sum karmic-moblin-remix-i386.iso
26c3177ae594a3713b0e318e12e91e1b karmic-moblin-remix-i386.iso

I assume the change is that the file is no longer in the page cache
