Currently, two CoordinatedTiles use the same UpdateAtlas in the same time. It is a bug that can crash in some platforms.

For example,
1. m_nonCompositedContentLayer->flushCompositingStateForThisLayerOnly();
2. CoordinatedTile::updateBackBuffer()
3. FrameView::paintContents()
4. FrameView::flushCompositingStateForThisFrame()
5. CoordinatedGraphicsLayer::flushCompositingStateForThisLayerOnly()
6. CoordinatedTile::updateBackBuffer()

#2 calls UpdateAtlas::beginPaint and #6 also calls UpdateAtlas::beginPaint before #2 is completed.

I think if this bug is resolved, above bug is also resolved.
