Yes, my bad.  However, I still believe that killall is a dangerous
command to use in a shell script since you can't be sure you won't kill
other processes (with the same name, for example).

Why would you switch off cpuspeed?  You can access all the files
in /sys/devices/system/cpu/cpu0/cpufreq while cpuspeed is running and
all your changes take effect immediately.  In fact, with cpuspeed off,
setting /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor is
meaningless.
The steps I described previously to echo to these files should be
performed while LEAVING cpuspeed ON.
