There was a thread on "unusually high load averages" when running under sched_ule, in January 2004.  Looking at this, "pagezero" is (one of) the culprit(s).  We had no provision for processes with P_NOLOAD set.  With pagezero not running at PRI_ITHD, kseq_load_{add,rem} count pagezero as another-normal-process, thus the "expected-plus-one" load reported in the above thread.
