Subject: popen, popen3, and leftover processes

I'm getting processes left lying around when I do things
like

   io = IO.popen("foo")  # or...
   inp, out, err = Open3.popen3("foobar")

I've tried such things as closing the io object, but to
no avail.

I see no way of retrieving the pid in either case.

What can I do?

Thanks,
Hal
