Tile rendering is now mostly parallel up to 4 procs.

Browse Source 
The initial recursive call for tile generation will spawn up to 3 extra
processes to work on each quadrant. It's not perfect yet since some
quadrants may have more or less work to do, and only 4 total workers are
supported.

Also, it waits for all chunks are finished before it dives into the
tiles, to prevent it from using more resources than requested.
