I do not think that this bug (with the ambiguous Gnus plugged/unplugged state) is the same as the wait_reading_process_output bug, and I'm not entirely convinced that the two bugs are related, but of course I might be missing something. I can now reproduce this bug (#28596) at will -- and without any apparent hang at all. So I think the hang I was experiencing while trying to get Gnus to behave itself was a red herring -- quite possibly I was running into the other bug while I was trying to get myself out of this one. And IIUC the wait_reading_process_output bug has been in Emacs for a while (forever?) whereas this bug exists in Emacs 26 but I have never seen it and cannot reproduce in Emacs 25. N.
