Take `custom-save-variables' as example.  It searches in `obarray'
for all symbols that should be saved:

<lisp/cus-edit.el, in the body of `custom-save-variables'>
     (mapatoms
      (lambda (symbol)
        (if (and (get symbol 'saved-value)
                 ;; ignore theme values
                 (or (null (get symbol 'theme-value))
                     (eq 'user (caar (get symbol 'theme-value)))))
            (nconc saved-list (list symbol)))))

The criterion could be a symbol in `obarray'.  Before
`custom-save-variables' searching in it, it first insure the symbol
is interned.

We can apply this for the other similar functions, such as
`custom-save-faces'.

My question is, if `custom-save-variables' signals an error, what
can the user do?  The user wants to kill Emacs at that moment.
Can the user load all customizations when she/he sees the
error?
