Doing clone() in libc that calls rfork(2) and doing all the stack setup should be pretty easy.. (Richard has done it already, yes?) On the other hand, the linux emulator needs it so there's a counter-argument for making it a proper syscall outright. Leaving the rfork(2) stuff unmolested and at least resembling it's plan9 origins probably has some merit - adding extra arguments would mess that up.
