Sorry, yes, that's what I meant.  I shouldn't have used the word fork
without further qualification, which specifically means the child
process has all the same data.  What's needed would traditionally have
been done by a fork followed by an exec, and popen would have done
something like that.  These days I think there's some more streamlined
ways to do it.
