One good thing the guys from Java 1.5 did was putting the modules in shared memory, so different JVMs running on the same machine can share the loaded modules.

So I was wondering... Is it possible in Perl? Maybe in Perl6? The dynamic nature of the language is something that makes it harder or even impossible?

UPDATE: Just to clarify, when I mean shared, it's in the sense of shared libraries, which are shared among unrelated proccesses, and not by one proccess and its children.

UPDATE2: Well... I was wrong... Searching for more information on what Sun calls "Class Data Sharing", I saw it only does it for some core libraries, namely, that in rt.jar and only for the Java Hotspot Client VM. http://java.sun.com/j2se/1.5.0/docs/guide/vm/class-data-sharing.html
