Use the subprocess module:
import subprocess
...
script = 'python'
args = (script, '/path/to/executable', ...)
env = { ... }
pid = subprocess.Popen(args, close_fds=True, env=env).pid
t = Torrent.objects.create(pid=pid)
...
Remember to store the pid for later wait()ing or you'll end up with zombies.
