Nicole: it's possible that bug 656120 has fixed this problem. Can you please try a nightly build (nightly.mozilla.org) and let us know if it has been fixed? Thanks.
I tested it in Nightly built on 22-Jun-2011. I did two runs. Nightly started with 36 MB. Here the list of the peaks and the result of the release 1. 7 min 62 peak 41 after 2. 5 min 51 peak 41 after 3. 10 min 97 peak 44 after 4. 3 min 64 peak 44 after 5. 9 min 96 peak 44 after 6. 4 min 63 peak 45 after 7. 9 min 98 peak 45 after 8. 3 min 65 peak 46 after mini peak, after 44 So there seems to be a 4-9-4-9 minute pattern, at least for this page. It's definitly much better than before. If someone has a explanation for the small memory arise (41 --> 44 MB) or could tell that this isn't correlated with the size of the page / communication-packages, then I would even say, it's solved completely. Good work! :-)

Heap size measurement tend to be pretty noisy in practice, so 3MB doesn't worry me much. I'm happy to declare victory here.
