Yes, this code was old.  Plus I didn't know what I was doing. :-)

I've put a new version in the same place that seems to work (as well
as it ever did) under CMUCL 18e+ (that is, CMUCL from CVS) and Garnet.
I have this fantasy that someone will look at it, get inspired, and
add a real stream listener to Garnet.

My experience in this area hasn't been too good.  I actually went
through the stream-listener exercise 3 times: once with CLUE, porting
their streams.lisp code to gray-streams under CMUCL, once with Garnet,
and once with something called CLINC which is a kind of precursor to
free CLIM.  I think the last one worked the best.

Then someone wrote a listener for McCLIM that really works.  I hate
him. :-)
