[Cosign-discuss] new factor - should the process fork?

[Liam H. <li...@um...>]

I'm writing a new factor.  I'm looking at a previous scripted factor, and
it includes:

    pid = os.fork()
    if (pid != 0):
        #This is the name of factor reported to cosign
        print('factor')
        sys.exit(0)

The author is no longer here.  Why would they do this?  Is this a good
practice to follow?
