pidof and killall look at the process name first, and the command line second.
The process name of kio_file is 'kio_file'.  The command line of
kio_file is 'kdeinit4: kio_file [kdeinit] file local:/tmp'

(see:  cat /proc/$(pidof kio_file)/status  and compare against
/proc/$(pidof kio_file)/cmdline)
