Do you mean that we should be using spawn on linux? Why? It doesn't seem it would make a difference here?

While talking offline, Abe brought up the point that the parent process could have imports that could carry over to the children with 'fork'. I'm not sure about that, but it seems fairly safe to set them all to 'spawn'.
