That's how it worked in Emacs-23, indeed.

Yes, that's a bug.

In Emacs-23, marking the window as dedicated via
display-buffer-mark-dedicated was handy but indeed had the disadvantage
of preventing the window's reuse by display-buffer.  I think in Emacs-24
this disadvantage is less serious because the completion code is a lot
more careful to not leave the *Completion* displayed too long.
So making display-buffer-mark-dedicated work (which we need to do in any
case) should be all that's needed to fix the bug.

But of course, if we can get the *Completions* window/frame deleted
without marking it as dedicated, that'd be fine as well.
