FYI, after I updated an SMP machine (with 4BSD) yesterday it got into a state where all processes were sleeping and the only running processes were the idle tasks, but nothing was apparently holding a lock. This is just after the most recent commit to kern_sig.c, so it's one possible candidate for the cause. I backed out this change, and so far it hasn't recurred.
