Impossible.  If there is a pointer to the object left over in a register or on 
the system stack, or an integer value than just happens to look like a 
pointer to an object, then the object will be retained by the conservative 
garbage collector no matter what you do. 

But, you are welcome to try to devise an solution to the guaranteed 
finalization problem that 50 years of GC research has been unable to find.  
Let me know when you have a patch. :-)

Cheers,

Rhys.
