   It is VMS, not EMACS, which is leaving RIGHTSLIST.DAT open.  When you (or
   EMACS) call a system service which accesses RIGHTSLIST.DAT it is left
   open until the image exits (under the assumption that you will be accessing
   it again).  This is so you get:

     OPEN ACCESS ACCESS ACCESS ACCESS ACCESS ACCESS ACCESS CLOSE
     ^^^^^^^^^^^                                           ^^^^^
     first call    2nd    3rd   ...                        image exit

   rather than:

     OPEN ACCESS CLOSE OPEN ACCESS CLOSE OPEN ACCESS CLOSE ....
     ^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^
     first call            2nd                 3rd         ....
