I've just tried but with sudo over TRAMP.  I had a message about the
lock that I stole and then Emacs created another auto-save file with
TRAMP naming (this file is also mode 0600).

I guess that using TRAMP is cheating here and that I should really be
another user using Emacs and trying to open this same file...  Then I
guess I won't be able to recover from (or write to) this auto-save file.
But does this kind of scenarios appear in real life?
