IIUC a user can either set

 `reusable-frames' -- Value specifies frame(s) to search for a
                      window that already displays the buffer.
                      See `display-buffer-reuse-window'.

to nil so the buffer will get displayed on the selected frame even if it
is displayed somewhere elese, or set

 `inhibit-switch-frame' -- A non-nil value prevents any other
                           frame from being raised or selected,
                           even if the window is displayed there.

to t.  The semantics of the latter is not very clear to me because with
most window managers Emacs cannot prevent a new frame from being raised
and selected (at least that's what I've been told repeatedly).
