sched_ule broke about a week ago. The following example shows an idle 4
CPU SMP box running -current from 2 days ago. Note the CPU percentages for
the idle threads:

$ top -Sb

Also, this box sits idle alot (like it is in the example above) yet the
load average now does not return to 0.00 like it used to.

WITNESS and INVARIANTS is turned off, ADAPTIVE_MUTEXES turned on.

There is something definately not right anymore.
