The separate processes would share memory including a part of the 
actual JVM code as well as much of the Java library classes if (and I'm 
pretty sure only if) you are running on OS X.  Apple has provided the 
technology to do this back to Sun and it will likely appear in a future 
version of Java.  At one stage Apple was suggesting it would likely 
appear in Java 1.5 but it seems to have slipped from there.
