intermittent commit: do not spawn doomsim instances to test rendering

Browse source 
Without spawning doomsims the SDL_UpdateTexture()+SDL_RenderCopy() way does
scale well: with 1024 non-spawned dooms I'm at 19.4 fps, 51.5 ms/frame.
A single core is maxed out all the time and it's nicely jumping between
cores.
