Find most CPU-hungry threads under Linux

It's pretty easy to find CPU usage per process (top, ps), but If you want to find top CPU users per thread there's a method:

$ awk '{printf "TID: %6u  %8u %8u %8u \t %s \n", $1, $14, $15, $14+$15, $2;}' /proc/*/task/*/stat | sort -n -k 5 | tail -10
TID:   3600     33700    11461    45161      (metacity) 
TID:   3612     38053     7716    45769      (nautilus) 
TID:   3634     65079        0    65079      (dconf 
TID:   3601     64168     4997    69165      (gnome-panel) 
TID:  17298    137525    15650   153175      (firefox) 
TID:   3840    168736    21351   190087      (skype) 
TID:  11622     76119   150472   226591      (multiload-apple) 
TID:   3616    492076    53810   545886      (gnome-terminal) 
TID:   3617    370649   220327   590976      (skype) 
TID:   1072    626086  1031732  1657818      (Xorg)

Results are sorted by cumulated CPU usage (user + system).
