If I understand your question correctly, it sounds like what you are looking for here is to be able to launch a list of scripts with the output redirected to files. In that case, launch each of your tasks something like this:

task = subprocess.Popen(['python', 'myscript', 'arg1', 'arg2', 'arg3'],
    stdout=open('output.log', 'w'), stderr=open('err.log', 'w'))

Doing this means that the subprocess's stdout and stderr are redirected to files that the monitoring process opened, but the monitoring process does not have to be involved in copying data around. You can also redirect the subprocess stdins as well, if needed.

Note that you'll likely want to handle error cases and such, which aren't handled in this example.
