multi-web-global-mode-buffers has a buffer  *Minibuf-1*
rfn-eshadow-frobbed-minibufs has a buffer  *Minibuf-1*
gnus-buffers has a buffer *Article nndraft:drafts*
gnus-buffers has a buffer  *Original Article nndraft:drafts*
gnus-buffers has a buffer *Summary nndraft:drafts*
gnus-buffers has a buffer nil
gnus-buffers has a buffer *unsent wide reply to Lars Ingebrigtsen*
gnus-buffers has a buffer  *gnus article copy*
gnus-buffers has a buffer  *nnmail message-id cache*
gnus-buffers has a buffer  *Gnus Backlog*
gnus-buffers has a buffer  *gnus work*
gnus-buffers has a buffer  *Gnus agent overview*
gnus-buffers has a buffer *Group*

And then I have to stop it with C-g because it hangs...

I had to restart emacs this morning, there are no more *Help* and
*Completions* buffers in the killed list. But there is "gnus-util.el".
