It seems like what you want is for multiple Racket programs to be able to share the same VM process, thus sharing memory. I think this would be useful in some cases, and I think people have investigated it in the context of Java. But it also has some drawbacks. For example, a crash in one program brings down everything. And SirMail and DrRacket can't run on separate cores. And both programs pause at the same time for GC.
Our whole claim is that mred eh mrracket is an OS. We should push it hard so that one error doesn't take down the whole thing. And I think we can. (I could even imagine a fake shell :-)
In general, the trend in VMs seems to be toward spawning more of them quickly (that's what Chrome is doing, and Java has worked on this), rather than sharing them more.
We're not there. When we are, we can revisit. _________________________________________________ For list-related administrative tasks: http://list.cs.brown.edu/mailman/listinfo/plt-dev
