Yeah, it probably would have helped if I included that, wouldn't it? :)
Here it is:
#!/usr/bin/csi -script
(use extras)
(use srfi-18)
(use tcp)
(define num-threads 2)
(define (connect port)
(let-values (((i o) (tcp-connect "192.168.1.101" port)))
(read i)))
(let loop ((port 9000) (threads '()))
(if (= (length threads) num-threads)
(for-each thread-join! threads)
(loop (+ port 1) (cons (thread-start! (lambda () (connect port)))
threads))))
