To support two (or more) VM instances per process, there must be separate class
instances, with their own static variables.  Each VM would have a set of threads
and probably their own heaps as well.

With libgcj each of the core classes are bound to global symbols.  I think that
makes it impossible to support more than one instance of a class per process.
