   7 /* Revised: Sat Apr 14 17:08:17 PDT 1990 (marvit@hplabs)
   8  *    Added hpux hacks to set and reset gid to be "mail" as needed. The reset
   9  *    is necessary so inc'ed mail is the group of the inc'er, rather than
  10  *    "mail". We setgid to egid only when [un]locking the mail file. This
  11  *    is also a major security precaution which will not be explained here.
  12  *
  13  * Fri Feb  7 16:04:57 PST 1992         John Romine <bug-mh@ics.uci.edu>
  14  *   NB: I'm not 100% sure that this setgid stuff is secure even now.
