Actually, I guess this include is wrong, but as far as I can tell this code is
child only. (?)

why do you say the include is wrong? it appears that this code is run in child
processes, so i assume you'll move this to content/child later?

Yah, that's what I meant (it's going child->common right now). It looks like
most/all of common/gpu could go to child/gpu?

theoretically, yes. there are just a bunch of includes now
