 ======  
  
     -   Fix case sensitivity problems in repository (just add an _Open method      -   Consider eliminating const CIM element classes.
         that ignores the case of the file).

         are in the same process. That is because the client cannot read          provider and repository end. Otherwise, all classes or instance
         anything as long as writeN() is blocked on a synchronous write.          to be enumerated, must be sucked into memory.
