This is because the idle process is always running (see "ps lax" outout).
Perhaps the bug is that top doesn't show the idle process or other interesting
kernel processes like the new interrupt processes.

I get these at boot time on one machine but not on another very similar
machine, and often after messing around with ddb. TSC timecounter in
all cases. I think they are not a serious problem or related to old
timecounter bugs, but they may be related to old bugs setting `switchtime'.
