I have been trying to install emacs 18.57 on our system and I would be
grateful for answers to the following questions.

1.  There was a program in release 18.55 called loadst which read the
    current load averages from /dev/kmem and passed them to emacs to
    be displayed on the status line when running display-time. This
    program was installed as setgid kmem. I now note that the
    functions for this have been subsumed into the code for emacs. On
    our system, there is no public read access to /dev/kmem. The
    questions is, if I install emacs as setgid kmem, will this affect
    the way emacs writes user's files? Ie. will files end up having
    the wrong group, and will this bypass protections on files
    belonging to kmem.

2.  When emacs starts up, it checks the termcap entry to see if the
    terminal type supports an application keypad. If it does, the
    terminal is set into this mode. If I suspend emacs, the keypad is
    not set back into numeric mode. If, however, I run a program which
    does change the keypad mode to numeric, when I start emacs up
    again from the background I have lost the application keypad. I
    think that if emacs is going to change the keypad mode, it should
    do this in a consistent manner. Also, some way of
    enabling/disabling the application keypad would be nice.

3.  When running emacs on an X terminal I can find no way of enabling
    the alternate keypad. The X terminal emulates a vt100 (from the
    $TERM environment variable). The vt100 termcap entry supports the
    alternate keypad (I get it if I start emacs with -nw on an X
    terminal).

Reply by mail if possible. Thanks a lot, Mark.
