Turns out not. The code is much simpler supporting just individual oop 
locations (variables) so I decided to go with the following interface:

sqInt oopVar; /* declare a global that we wish to track */

   oopVar = vm->nilObject(); /* don't forget to initialize it !!! */
   vm->addGCRoot(&oopVar); /* update it */

and to undo that
