When I switched to my -current box to implement LOCAL_PROC this
morning I noticed it was there indeed (unavailable on 4.0).  According
to unix(4) this would only work for SOCK_STREAM at connect(2) time,
however I'll check if that's what the code really does.  If that is
the case, it might be worth considering a modification to also allow
it on a per-datagram basis.

Unfortunately, I only noticed LOCAL_PEEREID after I implemented
LOCAL_PROC as I finally added the new #define to un.h :) and
LOCAL_PROC semantics are like LOCAL_CREDS ones.  I'll consider posting
a diff in a PR if I have to fix LOCAL_PEEREID to work with

Thanks again,
