I'd also like to implement a proper clone(2) ala Linux. We have most of the infrastructure in place already, using that and comparing with NetBSD's take on the subject should be fairly useful in the end. The main difference between clone(2) and rfork(2) is that clone() takes a stack argument and is more specific about certain sharing semantics. At present these are emulated via flags added into rfork's visibility, I think it would be cleaner to just use a proper syscall interface onto fork1() rather than bend rfork(2) even more.
