2649 times in 30 seconds totaling 1070 ns does not seem like much to me.
My idle laptop shows:

hmm ... good point.

...slowly catching up... ;)
I ran the lockstat command on the OI box at my office, just to have
another set of numbers to compare. Output:
admin@victor:~# lockstat -kIW -D 20 sleep 30

So it seems to be normal to have some kind of idle process on top.
Numbers seem to be roughly comparable...? However, compared to the
lockstat output of my box, there isn't anything with apci here...
