I consider tinkering with obarray's internals still too "advanced" to
prefer it to a simple generation of Lisp code that records values of a
few variables.  (And are you sure all of the information we record at
dump time is in obarray? I am not.)  The number of these variables is
not large, so finding them in the sources will not be hard.
