I think you are reading too much into my answer. I am not connecting to a
long running Python task. The subprocess module allows Python to invoke
other programs.
<http://docs.python.org/lib/module-subprocess.html>
The task that cron would be invoking is a python script (which invokes the
Python interpreter). It can then invoke other tasks using the subprocess
module.
