The following part of `pop3-read-response' is infinite loop because `(not
(search-forward "\r\n" nil t))' is t all the time.

      (while (and (memq (process-status process) '(open run))
                  (not (search-forward "\r\n" nil t)))
        (pop3-accept-process-output process)
        (goto-char pop3-read-point))
