Yes, this isn't the method I use but it seemed a good idea on first
thinking about it. I use Thor's GetTCP and SendTCP so it's easiest to
simply check for the names in the process list.

A safer option would be to have each script set a separate clip to 1
at the start and 0 on exit, then check that the sum of the clips is
zero.
