os.system[1] is not an asynchronous function. It returns as soon as the 
called command terminates, not earlier.

If you want to execute a command in a subprocess, use 
subprocess.Popen[2]. You can then later kill this process using 
Popen.kill()[3].

 >>> import subprocess
 >>> p = suprocess.Popen(["sleep", "10]) # sleep 10 seconds
 >>> p.kill()
