bug#16596: 24.3.50; unable to move cursor while newsticker fetching data

[Thierry Volpiatto]

Hi,
here a big regression compared with emacs-24.3, newsticker seems to
fetch its data synchronously blocking any movements in its buffer.
Also I see processes still open and fetching data continuously.
(I have to kill them manually)
Well very different behavior compared to emacs-24.3.

Here the relevant config I use for newsticker:

(setq newsticker-frontend 'newsticker-plainview)
(setq newsticker-retrieval-method 'extern)
(setq newsticker-show-descriptions-of-new-items nil)
