You shouldn't have to do anything special. Once the command has been added to the action stack, it is OpenDoc's responsibility. If an exception occurs in Undo or Redo, OpenDoc catches it and clears the action history. As part of that process it will call DisposeActionState for each of the commands on the stack.
