    Add purgeObj() to remove the symbol table entries for an object
    
    This allows us to replace an object without actually unloading the old
    object, which is necessary when we know we have references to the old
    object so it can't be completely unloaded.  Using unloadObj() would
    cause the GC (CheckUnload) to repeatedly and fruitlessly try to unload
    the old object.
