Ok, thanks.

This:
(defun srb-gnus-group-get-new-news (&optional arg one-level)
(interactive "P")
(with-timeout (1 (kill-buffer (nntp-find-connection-buffer
nntp-server-buffer))
(gnus-group-get-new-news))
(gnus-group-get-new-news arg one-level)))
(define-key gnus-group-mode-map "g" 'srb-gnus-group-get-new-news)

Is that different than what the above function does with the kill-buffer
sexp? (Not a rhetorical question, I know next to nothing about news
servers and their connectivity issues.)

Hm, I had understood from both Prashant Tak and Eric Fraga that the
problem they have is essentially the same as I do and what I reported in
that bug. But that problem doesn't seem to be understood. If by the
understood problem you mean the effect of nntp-connection-timeout,
doesn't that just mean using it isn't a real fix for the hang the three
of us (at least) are experiencing? That's why I thought other
approaches need to be considered and bug#52735 seems like the
appropriate venue for that. But I'm fine with continuing the discussion
here instead.
