Rendering is definitely happening during threaded_tile_processor. What
I think the problem is with your implementation is that
threaded_tile_processor will free and allocate the RenderResult each
time, removing any previous data. That code has to be refactored so
that you can do things in this order:

* create render result
* for each view
** create render database
** threaded tiles render
