qcmu (was: Attaching to a running CMUCL process)

Is anyone using QCMU?  I'm afraid that the package isn't
that well
documented, and as a result I haven't been able to figure
out how to
use it.

I've gotten as far as

% ./qcmu
qcmu: lisp listener socket: Connection refused

(I'm testing this on a PPC machine, which from the CMUCL
docs will
eventually cause me to run in to trouble, but I think right
now the
trouble is more conceptual.)

BTW, what I want to do with this program is described at 

 http://pla
netx.cc.vt.edu/AsteroidMeta/MUSN  

As noted there, I started asking questions about this on
UseNet in
June of 2006 (comp.lang.lisp, "Multiuser Lisp
Server?").  But I got
stalled out due to motivational issues shortly thereafter.

Now that I've thought more about the problem I see that it
ought to be
very simple, and I'm pretty intent on hammering away at the
problem
until it is finished.

Any help with QCMU or otherwise would be appreciated.

PS.  I was looking over the recent thread mentioned in
parentheses in
the subject line -- I too am interested in attaching to
running CMUCL
processes.  I'd be curious to know whether Denis
Papathanasiou was
satisfied by the lispserver info (if he's reading this).

PPS. Craig Ludington's offer for help with Swank might be a
good way
to go if somehow QCMU proves impossible.

Joe,

In the end, I wound up using detachtty/attachtty for this
(i.e. invoke
the process under detachtty, accessing the REPL using
attachtty when
necessary) and it really works well.

The only reason I raised the question in the first place was
because
the long-running process I had wanted to access was not
launched under
detachtty initially, and so I wanted to see if I could get
inside its
REPL w/o stopping it and relaunching it under detachtty.
