+- secondary indices on the "lisp" side : minor / nil

+- create 2 DBs per sorting function: primary and secondary,
+without and with duplicates.

+- in addition to the usual lexicographic sorter, create a
+"lisp" version -- sorts primitive types (numbers, strings,
+symbols.)  use http://oss.software.ibm.com/icu/ for 16-bit

+- equality joins have to be done on the lisp side:

 this is not particularly a bug but: if you redefine the
 persistent-object class, you will mess up any existing
 persistent classes you've made.
