    (ZWEI:SAVE-ALL-FILES) is a win. I suggest that another function also be
    defined, one that doesn't attempt any interaction with the window system
    and can be used from the cold load stream, with minimum console
    interaction.
SAVE-ALL-FILES only sends messages to streams.  So, if called from the
cold load stream, it only requires that the file system still work,
which is no better than your suggestion.
