    Re:   flavors like a 3600

    Richard Zippel, an MIT prof working for Symbolics at the time rewrote
    flavors.l from scratch using fclosures and passed it on to us.

Just to clarify this a bit, I didn't rewrite it from scratch, I took the
Lisp machine's flavor code and forced it to run within Franz.  This was not
trivial and in doing it I lobotomized the code slightly by making it use
fclosures.  (Flavors used to use closures but this replaced by mapping table
magic after a while to speed things up.  I just took a step backwards.)  To
use my flavor code in a performance critical situation, I would put the
mapping table stuff back in, but that would take a few weeks of work, it is
quite hairy.
