:Log Message:
:- Merge sched_pstats() and uvm_meter()/uvm_loadav().  Avoids double loop
:  through all LWPs and duplicate locking overhead.
:
:- Move sched_pstats() from soft-interrupt context to process 0 main loop.
:  Avoids blocking effect on real-time threads.  Mostly fixes PR/38792.
:
:Note: it might be worth to move the loop above PRI_PGDAEMON.  Also,
:sched_pstats() might be cleaned-up slightly.

Something is funny with this new merged "load average" calculation.

        % uptime
         2:06PM  up 33 mins, 1 user, load averages: 11.04, 11.03, 9.96
        %

It should be showing about a tenth of that.

This is i386 with SMP (Core2Duo).
