    (defun test-cleanup ()
      (let* ((cleanedp nil)
             (thread (threads:make-thread
                      (lambda ()
                        (unwind-protect (sleep 999)
                          (setf cleanedp t))))))
        (sleep 0.5)
        (threads:destroy-thread thread)
        (sleep 0.5)


ABCL-1.0.0 and ABCL-0.27.0 return NIL.

Other implementations I tested all return T -- Allegro, Clozure,
LispWorks, SBCL (changing "threads" to "bordeaux-threads").

Of course this isn't a bug since ABCL is free to do what it wishes.
Does ABCL wish that?
