That's the theory. Unfortunately, reality is more brutal. Perl uses reference-counting garbage collection. Which means that if a process even looks at a chunk of data, the reference count gets incremented. Which touches the memory page. Which means no sharing. Embedded Perl helps a bit. But unfortunately, it doesn't help anywhere near as much as it should help because of Perl's #*&$*&#$ reference-counting.
