I guess you are using wish-wish (which I first called lisp2wish, but that
name was already owned by another package, doing a similar thing).
The problem stems from a bug (mea culpa) in CLOSE-PROCESS-STREAM.
The following definition fixes the bug:

(defun CLOSE-PROCESS-STREAM (stream)
  #-:KCL (when (typep stream 'two-way-stream)
           (close (two-way-stream-input-stream stream))
           (close (two-way-stream-output-stream stream)))
  #-:KCL (close stream)
  #+:KCL (close-program-stream stream)
  #+:ALLEGRO (sys:os-wait))
 
(I did not realize, that closing a two-way-stream does NOT close its
constituent streams.)

There is a fixed version of with-wish in
