Surely, restarting X was overkill.

Ah, now I get what you're driving at. Yeah, they're different, but
there's magic in them thar functions. Consider C-y, which is bound to
the command yank, defined in simple.el. If you look at the definition
(easy: just C-h k C-y and click on the _simple_ link in the help
window) you will find that yank calls current-kill to get what it is
yanking, and current-kill in its turn will funcall
interprogram-paste-function, which is a variable that typically (on X)
has the value x-cut-buffer-or-selection-value. And that function is
described as follows in x-win.el:
;;; Return the value of the current X selection.
;;; Consult the selection, and the cut buffer. Treat empty strings
;;; as if they were unset.
;;; If this function is called twice and finds the same text,
;;; it returns nil the second time. This is so that a single
;;; selection won't be added to the kill ring over and over.
In summary, if you set interprogram-paste-function to nil then I think
you have completely severed the connection between the kill ring and
the X selection, and then you will always have to make a conscious
choice between the two. But that seems to be what you want. Try it,
and see if it does what you want. Heck, I may want to try it myself.
(No apology for the lengthy answer with such a brief solution. I try
to educate people, teach them how to find answers on their own, rather
than just telling them the answer. Occupational hazard.)
