[Jagannathan, Suresh]

Actually, I believe that C can continue to hold onto
Java objects even after it returns.  Since these objects
have been registered as global roots, they will not be
GC'ed.  However, when the objects are no longer accessible
they must be explicitly deregistered by the appropriate
Java stub.  So Matthew's point about keeping everything in
the indirection table live until it is explicitly deleted
is the correct interpretation, I believe.
