weird cpu usage in -current

Hi,

Just tried out tools/tools/http on the local machine and got the
following output from top

last pid: 74521;  load averages:  2.14,  0.56,  0.20    up 0+15:46:19  01:10:57
166 processes: 7 running, 159 sleeping
CPU states: 41.0% user,  0.0% nice, 46.9% system, 12.1% interrupt,  0.0% idle
Mem: 142M Active, 248M Inact, 74M Wired, 19M Cache, 59M Buf, 3032K Free
Swap: 512M Total, 512M Free

  PID USERNAME  THR PRI NICE   SIZE    RES STATE    TIME   WCPU COMMAND
67492 www        24  76    0 32948K 24764K RUN      0:09 507.03% httpd
62977 www        23  76    0 32804K 24572K RUN      0:09 422.46% httpd
74517 root       61  76    0 19232K  4276K RUN      0:03 14.16% http

It looks just too weird. Is there a proper explanation for this
sympton? I use ULE btw.
