* Thanks Cameron,
That worked, I hadn't used threads before and they were what I needed.
* Thanks Sebastion,
I thought I had tried this:
system("some_command&")
and it didn't work -- but it was late and I needed to sleep -- today that works fine -- so obviously I wasn't thinking as clearly as I could have been.
* Thanks 7stud,
IO.popen is interesting, I'm playing with your simple test programs and reading chapter 11 in the Pickaxe book.
