Hunting kernel lock and interrupt latency.
Too much of the kernel still runs with the kernel lock, which is bad for performance -- and especially for interactive system responsiveness, since most of wscons including keyboard and mouse input still use the kernel lock. On single-CPU systems, the same problem arises with interrupt latency on its own...
