Yes, using green threads for ray tracing is basically nonsense, since keeping actual threads busy is no overly difficult.

It's not nonsense if, to render each pixel, you issue an HTTP request containing the scene/eye data and requested pixel coordinate, and wait for a response to come back from your magic render farm that lives in "the cloud". Now your "ray tracer" is totally I/O bound! :-)

Not sure if /s, but, to rasterize a 1920x1080 image you would make 2073600 HTTP requests? Sound reasonable.

Double that if you want to PUT the pixels on a screen.
