Well, I'm not sure if I understand exactly what you are asking, but witness only does lock order checks when you first acquire the lock. Any recursive locks will skip the order checking altogether since recursive acquires can never block. Similarly, trylock operations also stick order checks altogether since they can never block either. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
