I wrote a quick and dirty hack to paper over the Lispworks/SBCL differences, and the basic tests (from test.lisp) seem to work fine now with SBCL 0.9.16. I haven't committed the hack yet, because I still get an error with SBCL for one of the schema update tests. I'll try to debug that one too. Arthur
