Didn't quite hit the 1gig mark, but it was on it's way there. I had 2 videos buffering, and about 4 random articles open, and it was started to stutter and slow down, any higher and it would have crashed. In fact, it hit about 850 before I shut it down after making the screenshot
You can also see a much small version of the flash process running near the bottom of the list, but that's like 5k
