Ah indeed, that's how fstat(1) does it. And it's even more permissive than
on Linux because my non-privileged user can see the wd of all processes,
even root's.

But it will require linking tmux with -lkvm on OpenBSD. Is that okay?

Works for me.

So, if linking with -lkvm is acceptable I'll add support for OpenBSD and
send an updated patch.
