Er, this is the normal behaviour in FreeBSD-3.0 through FreeBSD-4.8, so you shouldn't have waited more than negative 4 years for it :-). The strict implementation of this behaviour in these releases causes priority inversion problems, but the problems apparently aren't very important. The scaling of niceness was re-broken in -current about 3 years ago to "fix" the priority inversion problems. This is with SCHED_4BSD. SCHED_ULE has larger problems.
