Right. How about this: remove the :handle-background argument and
allow the :init-fn to return NIL, meaning "I don't expect any input".

Then the dedicated-stream's INIT-FN can return NIL to avoid an endless
loop. Sound like it would work?

I hadn't realised how much variation there is across Lisp networking
interfaces when I defined that interface.

BTW, do you know a way to run LispWorks Personal Edition without the
GUI? It's driving me nuts :-)
