We don't think we're getting any benefit from RenderLayer being arena-allocated, and it adds code complexity.
How is RenderLayer different than the other Render* classes WRT usefulness of being arena-allocated?
There don't tend to be that many RenderLayers on most pages (tens - hundreds, not thousands).

This caused crashes on tests (debug and release WK2). Very strange that EWS didn't catch it, was the landed patch identical to the one posted here?
