It seems that killing the processes (nnimap, nntpd) each time a group is
quitted avoid a lot of C-g'ing, especially with tethering:

(defun tv-gnus-kill-all-nnimap-procs ()
  (loop for proc in (process-list)
        when (string-match "\\*?nnimap\\|nntpd" (process-name proc))
        do (delete-process proc)))
(add-hook 'gnus-exit-group-hook 'tv-gnus-kill-all-nnimap-procs)
(add-hook 'gnus-group-catchup-group-hook 'tv-gnus-kill-all-nnimap-procs)

Not perfect but it helps.
