Still only accurate for libthr, though, right?

I sort of like Solaris' prstat output, where the thread count is after
the command:

   PID USERNAME  SIZE   RSS STATE  PRI NICE      TIME  CPU PROCESS/NLWP       
  3120 dnelson  9320K 7256K sleep    0   19   0:00:01 0.3% pike/2
  3169 dnelson  4800K 4440K cpu3    59    0   0:00:00 0.2% prstat/1
  3144 dnelson  4192K 2936K sleep   59    0   0:00:00 0.1% zsh/1
 17037 root       89M   26M sleep   29   10   3:02:52 0.1% java/23

I also find myself asking exactly what our CPU column really
represents.  Is it any use at all?
