You should have tried #1 and #2 with emacs -Q. Otherwise, your private
settings will shadow #1 and #2 (I tested #1 and #2 here but would like a
confirmation).

Since you do set `pop-up-frames' to non-nil you have inirectly confirmed
that it works for your setup.
You did not report whether it works for `minibuffer-auto-raise' nil.
Can you look into that?

No. The crash happens because the following assumption in frame.c
/* We know that there must be some frame with a minibuffer out
there. If this were not true, all of the frames present
would have to be minibufferless, which implies that at some
point their minibuffer frames must have been deleted, but
that is prohibited at the top; you can't delete surrogate
minibuffer frames. */
if (NILP (frame_with_minibuf))
abort ();
does not always hold during the exit dialogue. And it's bad because it
crashes Emacs when I try to avoid the exit because of a running
subprocess.

Trivial. At the time you wrote the "fixes" you had "fixed" it already
by doing something else. Now you "just" have to find out what else you
did then ;-) Are you sure you ran your changes without my file loaded?

If you use Emacs 24.1 without my changes, then `list-processes' will pop
up a new frame and give it focus. When it now asks the `y-or-n-p'
question you _are_ lost if the new frame does not have a minibuffer and
you can't redirect it to one.

Try explicitly redirecting the focus from the new frame to the
minibuffer-only frame via `redirect-frame-focus'.

Une solution peut en cacher une autre.
