I guess that the ksmserver would be running shutdown after completion of 
logouts.

You could try 2 as the third parameter.
According to KApplication's API docs it is the value for forced shutdown.

But I guess if you want to shutdown at all costs, it would be better to have 
the power off call the standard shutdown process and put the dcop call for 
session logout and saving into a runlevel script, which waits for a maximum 
time before letting the shutdown progress to the TERM and KILL stage.

Cheers,
Kevin
