We've had a lot of bugs in the past with compositing turning off or the GraphicsLayer tree being mutated during painting.  See https://bugs.webkit.org/show_bug.cgi?id=54707, http://trac.webkit.org/changeset/45715/trunk/WebCore/rendering/RenderLayer.cpp and others.  We should add ASSERT()s to catch this case and some test cases to hit the areas where we've seen this happen in the past.
