> I found that chart a bit hard to read, but I think it's saying that we're spending a ton of time inside callTheAdoptionAgency, which is correct.  Another option is to reduce the depth of the test case.  I suspect a depth of 100 would be a sufficiently pathological test case.

Yep, I would say basically it spends 82.82% of the time in callTheAdoptionAgency, divided this way:
   - WebCore::ContainerNode::appendChild 40.74%
   - WebCore::Element::attach 36.54%
   - WebCore::HTMLTreeBuilder::reparentChildren 5.21%

But must of this calls end up in WebCore::Node::createRendererIfNeeded one way or another, where 71.28% of the time is spent, and gettig the style is more than half of the time creating the renderer (WebCore::CSSStyleSelector::styleForElement)
