The compositor / renderer thread puts stuff on the screen by mutating NativeLayers and then calling NativeLayerRoot::CommitToScreen().
The main thread also calls NativeLayerRoot::CommitToScreen() sometimes.
In theory, this has the potential to happen in the middle of a composition. At that point, the state of the window's NativeLayers would be inconsistent.
We should stop the main thread from committing in the middle of a composition.

Don't call CommitToScreen() on the main thread while another thread is compositing. r=jrmuizel
