Details 
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.

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.
