This should help find some bogus locking. There is at least one place where sigacts locking trips this assertion. I will try to work on cleaning up that and other problems that surface today from this check. I also need to add a KASSERT() to msleep/cv_wait* that we don't try to sleep if we are already on a sleep queue. It seems that using ptrace can trip that as well. :( -- John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/
