there is a noticeable drop in dromaeo css for linux32:
http://graphs.mozilla.org/graph.html#tests=[[72,131,33]]&sel=none&displayrange=7&datatype=running

I did some retriggers:
https://tbpl.mozilla.org/?tree=Mozilla-Inbound&fromchange=894b7372561d&tochange=4a3a302f1f31&jobname=Ubuntu%20HW%2012.04%20mozilla-inbound%20talos%20dromaeojs

and the lucky patch is from bug 1057219.  It is not all bad, if you look at the graph we bounced back, but we never backed out that patch.

I really want to document our regressions (purpose of this bug), and not back things out.  If we determine that the patch in bug 1057219 could be optimized we could probably realize a win!
Bug 1057219 is a minor incremental GC correctness fix and there's no way it legitimately caused a regression.
This has been shipped, I am going to mark this regression as wontfix.
