Thank you for the detailed explanation, and I think applying your patch will be
all right -- 7 years is a long time in the security-conscious OpenBSD world. It
would probably need an update to the NEWS file, though.
Eli, do you have any objection to the patch by Yasuoka-san, assuming that it
limits the OpenBSD support to version 5.3 or newer?
Presumably the patch would be for Emacs 28, unless there are strong
security/reliability reasons for Emacs 27.
