Like I said, I'm not a LISP programmer -- it's all yours, feel free to
change what you want.

The only way I currently use it is as part of (display-time), so I don't
need any caching myself -- it runs once a minute as is.

It is not setgid for linux and solaris, it is setgid for the others.  Whether emacs
works as is for linux and solaris I don't know, but I presume it does not
work for the other OS's -- definitely not for AIX 4.3.
