Something like this?

  in = Fpipe()
  out = Fpipe()
  Fforce(STDIN, in)
  Fforce(STDOUT, out)
  Pexec(100,"old_shit.tos", 0, 0)

  Communicate with the child here using the in/out pipes.

  Fclose the pipes and restore stdin and stdout when the child exits. Btw. is this necessary? If I don't close the pipes when the child exits, will stdin/stdout of the next child I Pexec be redirected? I don't intend to run several childs concurrently, but I might need to run several in sequence.
