I could be wrong, but I think sleep-for doesn't do what you think it
does.  In particular, sleep-for doesn't call timer functions, which is
needed to toggle the connected-p flag.  Try sit-for instead.

Consider something like:

(lexical-let ((hook nil) (done nil))
  (setq hook (lambda ()
                (remove-hook 'slime-connected-hook hook)
                (setq done t)))
  (add-hook 'slime-connected-hook hook)
  (while (not done)
    (sit-for 1)))

Again I could be wrong, but apparently you are trying to restart the
Lisp process and connecting to it.  Have a look at
slime-restart-inferior-lisp(-aux) to see how to properly kill the
