This is not a problem. The two instances will share code pages (in most
systems) but otherwise, there is no relationship. They each have completely
separate data pages.

If Java doesn't provide a way to clean up when the process exits, or when a
class is unloaded, then it could be problematic. OTOH, I kind of find it
hard to believe that we are the only C++ code out there that is wrapped by
Java and which does not provide for arbritrary de-initialization, right? How
are other people in the Java world dealing with this situation?
