BTW, here's a simple function to demonstrate the problem:

  (defun foo ()
    (restart-case (break)
      (use-value (x)
        :interactive (lambda ()
                       (format *query-io* "Value: ")
                       (list (read *query-io*)))
        x)))

Call it and select the USE-VALUE restart. I see the "Value: " prompt
in the REPL buffer but after I type 10 and hit enter nothing happens.
