Hmm, try this:
Code:
alarm_file_array="test1.alarms test2.alarms test3.alarms test4.alarms"
for file in ${alarm_file_array[@]}
do
        (   exec 0</dev/null # stdin
            exec 1>/dev/null # stdout
            exec 2>/dev/null # stderr
            trap "" HUP
            tail -f $file |awk 'NR>10' >> ${file}.out ) &
      disown
done

trap "" HUP works to prevent child processes dying with SIGHUP in my shell. Any more complex trap won't work, since child processes can't inherit actual shell code from the shell, just SIG_IGN.
