FrameView->m_lastPaintTime is only updated from FrameView::paintContents, not RenderLayerBacking::paintContents. This causes m_lastPaintTime to never get updated in the tiled drawing case. This can cause horrible things, like the HTML parser incessantly yielding even after the page has always painted, on a page with lots of inline <script>s, etc.
