Yes. See also the thread starting here:

Here's an easy solution:

 (define (system/output command-string)
   (let ([p (open-output-string)])
     (parameterize ([current-output-port p])
       (system command-string))
     (get-output-string p)))

Most of the work you were doing (or would be doing to avoid deadlock)
is in `system' already.
