Not to suggest anything particular to Mark, but rather as a general  
comment: I wonder how many of the "1.7.X no better" can be attributed to  
the replace-on-reboot failure up to and including setup 2.693. If people  
rely on that rather than running "uname -a" or similar, those that were  
told to reboot may be unaware they're using the older version.
