Looks like there's a leak in the getDirtyRects function in WKCACFLayerRenderer.cpp:

<http://trac.webkit.org/browser/trunk/WebCore/platform/graphics/win/WKCACFLayerRenderer.cpp?rev=59684#L455>

If we bail out early after calling CreateRectRgn, we forget to destroy the region. (Note that the extremely similar code in WebView.cpp does not have this bug, because it uses OwnPtr.)
