Well, so long as you never return from the idle function (or input function)
in the forked task - and never call another GLUT/OpenGL function from within
that fork, you should be OK.

I guess I'd make sure there are no timers or anything running when I forked
and I might even un-register all the GLUT callbacks before doing the fork.

I think it'll be fine.
