Processes launched are not killed when I kill ppss.sh

[GoogleCodeExporter]

What steps will reproduce the problem?

[psarkar@teentaal ppssTrial]$ cat largeLoop.sh 
#!/bin/bash

N=0
PN=$BASHPID
while (( $N < 1000 )); do
   N=$(( $N + 1 ));
   echo ${PN}_${N};
   sleep 1;
done

[psarkar@teentaal ppssTrial]$ head -5 joblistNumbered.txt 
/tmp/ppssTrial/largeLoop.sh 1
/tmp/ppssTrial/largeLoop.sh 2
/tmp/ppssTrial/largeLoop.sh 3
/tmp/ppssTrial/largeLoop.sh 4
/tmp/ppssTrial/largeLoop.sh 5
[psarkar@teentaal ppssTrial]$ wc -l joblistNumbered.txt 
170 joblistNumbered.txt
[psarkar@teentaal ppssTrial]$ \rm -r ppss/
[psarkar@teentaal ppssTrial]$ ps | grep largeLoop
[psarkar@teentaal ppssTrial]$ 
[psarkar@teentaal ppssTrial]$ ppss.sh -f joblistNumbered.txt -c 'sh $ITEM'

What is the expected output? What do you see instead?

The above shows the bash-shell interactions. As you can see,
even after the ppss.sh process has stopped with a Ctrl-C, the 8
processes launched are still running.

What version of the product are you using? On what operating system?
  . ppss version 2.4.1 on Fedora 11, intel Xeon quad core w/ hyperthreading

Please provide any additional information below.

Thanx for your input, this must be fixed.

In the upcoming version of PPSS this will be fixed. After some work I found a
solution to make sure that all children are killed when PPSS itself is killed 
using
ctrl-c. 

The downside is some cosmetic issues, however, everything is killed properly.
