Third, once you managed to truly separate interpreters, you *will* have to marshal objects across interpreters, as there won't be any shared ones. It's in the same address space, but you still would have to do marshalling, or else you might introduce sharing again.
I saw a talk today in which the presenter was talking about "guaranteed transfer of ownership" enforced by the language runtime. Essentially, it was a technique to allow a data structure to be passed from one thread to another, with a guarantee that there would be no heap pointers under control of the old thread pointing to anywhere in the data structure. When ownership is transferred, the old thread loses all visibility within the data structure, and the new thread now gains visibility of the structure. This was used to implement a non-copying message passing framework.
