One thing I've noticed is that NetBSD moved the setting of groups/uid/gid earlier to inside notify() (https://github.com/NetBSD/src/commit/46b017828cee516770586497237aed6182b1decf). I think failing earlier is also a good move.

Not a bad idea, can follow up with that (and check for any other improvements from NetBSD or OpenBSD)
