kill_delay

I can't seem to get the kill_delay attribute to work. I have kill_delay = 30. Submitting the following script (and then qdel-ing it) indicates that the time between SIGTERM and SIGKILL was 5 seconds. I see the same behavior if I set kill_delay at the server and/or queue level. Any suggestions?
I have pbs_version = 2.1.6 and Maui version 3.2.6p19.

--- SCRIPT ---
#!/bin/bash
trap cleanup SIGTERM
function cleanup {
    while :
    do
      date
      sleep 1
    done
}
sleep 1h
