"What are you worried about? You have 1GB of RAM. 72MB won't make a pinch of difference to your benchmark scores. Even still, you should be looking at the Mem Usage for your Processes if you want to know that that 72MB is being used by."

You may have a point. Strangely enough, the total amount of ram my processes are currently taking is only 32 megs. But Windows reports 81 megs taken up.
