Gensym (aka LMI) has developed an expert system shell (and thus I
assume applications) called G2 which satisfies your constraints.  I seem to
remember that it operates in a GC-less mode.   That is, they've
written their code so that it doesn't create garbage (I beleive they
explicitly deallocate conses et al) and they turn off (dynamic,
ephemeral?) GC.
