Attached jprof seems to show a lot of time being wasted in JS_GC when I am opening new windows (opened several dozen in a row). How can we get rid of (reduce) GC calls in SetNewDocument and SetupNewViewer? The default page is about:blank. See also bug 28639 (closing windows), and 30660.
Opening windows also gets slower and slower. First window takes about 0.3 seconds (time displayed status line), window 31 took 2 seconds to open.
Please also test bug 27574 if this gets fixed. Good catch Marko!

I suggest marking it depend on 42321 (perhaps some others mentioned there too).
As was done with related bug 42321, would like to redirect to DOM Level 0 -

We should really try to reduce the calls to GC when opening new windows, nominating for beta3. I had a quick look and it looks like we're calling GC 3 times for every new document we load or for every new window we open, seems like once would be enough.
