Hi Ralf,

Here are steps to reproduce the bug.

1. Add the following lines to ~/.gnus.el
    (gnus-demon-add-handler 'gnus-group-get-new-news 2 t)
2. fire up gnus
3. cut the network

Then when demon tries to get new News, emacs hangs. What's outrageous is
Ctrl-g won't be able to stop the process.

If you put the network back on, emacs will come to life again.
