How would that work? The directory beneath which openat is looking is

you'd have to pass a different value for "open relative to fd#5" and
"open relative to fd#5, but beneath it only", which doesn't sound
hugely elegant to me.

Yeah, it won't work for an explicit directory - I was thinking of
working relative to $CWD.
