Its not possible with os.system because os.system runs the called
program to completion in a separate process. You would need to
mess about with threads and process ids to do it that way. However
if you use popen() (or maybe popen2()? )you should be able to send
a Ctrl-C character to the process. However whether that actually
terminates it will depend on the OS, the process and whether
Ctrl-C is being caught anywhere. But at least there's a chance
of it working!
