Should we repeat too this when repeating PaintContentsToDisplayList above, so
that the cost of this caching is correctly factored into record time
measurements?

[Stephen Chennney, 2015/03/06 17:51:11]

The loop above is only for debug rendering slowdown. It's not the method used to
repeat for record time measurements; that call this entire method repeatedly. So
I think we're fine here.
