If you're using Python>=2.4 you could use the subprocess module.

import subprocess
child1 = subprocess.Popen(["./TestTool"], cwd="/home")
child2 = subprocess.Popen(["sh","run.sh","load.xml"], cwd="/usr")

Popen objects have a pid attribute. You don't have to use os.system to  
kill them; use os.kill instead.
You'll notice that I leave out the final &, because I don't know how to  
start a background process without using the shell. But I think you can  
use: bg [pid], afterwards, to get the same result.
