This is not directly related to your issue, but I find it useful in  
the IDE when testing/degugging multi-threaded code to be able to send  
output to the IDE listener. I'm sure Gary or someone else from Clozure  
will correct me if this is a bad idea, but I've been doing this:

(define-symbol-macro *listener-output*

which allows things like

(process-run-function "whatever"
                         (lambda ()
                           (let ((result (something-time-consuming-on- 
                             (format *listener-output* "result is ~a~ 
%" result))))

Of course if one does this the output from multiple threads will be  
unpredictably interleaved in the listener.
