Most users consider this a good thing.  It makes it easy to get things back
that you delete, although I suppose the advent of unlimited undo's has made
this less important than it was in the old days.

I don't think there's a built-in option for this.  You could advise all the
commands that you don't want to save, with something like

(defconst disable-kill-ring-advice
  (ad-make-advice 'disable-kill-ring nil t
		  '(advice lambda ()
			   (let ((kill-ring nil))
			     ad-do-it))))

(defun disable-kill-ring (function)
  (ad-add-advice function disable-kill-ring-advice 'around 'first))

(mapc 'disable-kill-ring '(kill-word backward-kill-word kill-line ...))

You did not 'delete' but 'killed' ;-)

See delete-region vs kill-region.

But I'm afraid that there's no built in delete-word in Emacs.

Don't know anything about xemacs.

What about the mini-buffer window?  I don't think anyone wants to use
killed words from that in any of the main buffers.  Is there any way
to turn that off?

Actually, I sometimes do.  For instance, an easy way to get the filename of
the current buffer into the file is with:

C-x C-v C-k C-g C-y

Also, when doing things like query-replace, I'm very likely to do some
kills while typing the old string and yank them into the new string.

It's not built-in, but this should do the trick:

(defun my-delete-word (arg)
  "Delete characters forward until encountering the end of a word.

With prefix argument ARG, do this that many times."
  (interactive "p")
  (delete-region (point) (progn (forward-word arg) (point))))


(defun my-backwards-delete-word (arg)
  "Delete characters backward until encountering the end of a word.

With prefix argument ARG, do this that many times."
  (interactive "p")
  (my-delete-word (- arg)))

Bind to keys of your choice and have a blast.
