That seems like a bug of sorts, but I think it's a symptom of PR
17171; the problem is not closing the slave per se but that there's
unread data on the master end. See that PR for a more comprehensive
explanation (and arguably clearer test case) that I posted some time

it would be good to fix it but given that the tty code's a maze I
think the prospects for an easy fix aren't that good.
