No, not draft 10. ISO/IEC 9945-1 ANSI/IEEE Std 1003.1 Second Edition 1996-012-12 as published. I have that sitting on the desk next to me, so I'll update the user-space threads to match the kernel thread implementation. I need to continue using the user-space threads on FreeBSD/Alpha for the forseeable future (unless someone wants to whack kernel threads into NetBSD's alpha kernel).
