alright, i might have found the root cause. when we declare EOF, we're not necessarily setting the input poll fd high. as a result, if the EOF comes at the end of an input burst, and we rely on such notifications, we miss it.
https://github.com/dankamongmen/notcurses/issues/2521 has more details. i need to rerun the autopkgtests with NOTCURSES_LOGLEVEL=7 to confirm this. Paul, is that possible to do without uploading a new growlight package? i think i've got this just about all figured out, and would appreciate another week or so to get it resolved, if that's doable.
