No, I suggested it because I wouldn't seriously consider keeping an
installation where backend start takes 5s.  If the address conflicts are that
persistent, I'd fix the bug or switch operating systems.  Therefore, we may as
well let it fail at that duration, thereby showing the user what to
investigate.  Startup time of 0.2s, on the other hand, is noticeable but
usable; I'd prefer not to fail hard at that duration.
