------- Comment #1 from webkit at mattlilek.com  2008-09-02 15:48 PDT -------
Definitely confirmed with r36029 debug build on Leopard - it ate into the
second core of my machine and the default sample from Activity Monitor was over
100 MB:

Total number in stack (recursive counted multiple, when >=5):
        115201       WebCore::RenderBlock::isSelfCollapsingBlock() const
        7234      
WebCore::RenderBlock::markAllDescendantsWithFloatsForLayout(WebCore::RenderObject*)
        5980       WebCore::RenderBlock::layoutBlock(bool)
        5979       WebCore::RenderBlock::layout()
        5899       WebCore::RenderBlock::layoutBlockChildren(bool, int&)
        452       WebCore::RenderBlock::collapseMargins(WebCore::RenderObject*,
WebCore::RenderBlock::MarginInfo&, int)
        450       WebCore::Element::recalcStyle(WebCore::Node::StyleChange)
        446       WebCore::RenderBlock::calcPrefWidths()
        445       WebCore::RenderBox::minPrefWidth() const
        444       WebCore::RenderBlock::calcBlockPrefWidths()
