No! Remember that we're about to be blessed with 1.3, which is known to
have extensions to Preferences. They'll probably extend the length of the
file to store this new stuff.  Everyone doing something with
sizeof(Preferences) or whatever will be ok. Anyone *depending* on the
old length remaining forever the same will be out of luck...broken
software under 1.3. Sigh...history repeats itself.
