This is not enough. You also have to add a catch to LispThread.

  (threads:make-thread #'(lambda ()
                           (let ((f nil))
                             (tagbody (setf f (lambda () (go foo))) foo)  
                             (funcall f)))
                       :name "foof")

And the created thread will die miserably in solitude.
