----------------------------- (8/21/05) ------------------------------

1) Reading 'rb_ivar_get' in VARIABLE.C
   ------------------------------------
   a) If OBJECT, CLASS, or MODULE
        if iv_tbl and st_lookup ok - return value
        (no sweat)

   b) If FL_EXIVAR Set then Instance Variable will be
      available in 'generic_iv_tbl' 
     **(Is there a possible race condition with GC that can cause
        the bit to be set and no Instance Variable available?

   c) Now Children  - there is a test for SPECIAL CONSTANTS
      **If the current Object is a special constant, then the
        function 'generic_ivar_get' is called???
        WHY - it ONLY returns a value for an Instance Value in
              the 'generic_iv_tbl'
        I could not figure a way to cause an Instance Value to
        be a Special Constant?  Is it possible?

        If it is - Code Fragment please!
