I missed Patrick’s reference to his peektest.c program the first time - whoops - or I’d have just run it myself!

On version 10.10.5, x86_64 architecture:

jkh at katana-> ./peektest
peek len: 0 errno: 0 flags: 12
recv len: 20 errno: 0 flags: 0

So yep, that’s the “reasonable behavior” from a UNIX2003 conformance perspective.
