stolen directly from Open3::open3.rb!
open4.rb: Spawn a program like popen, but with stderr, and pid, too. You might also want to use this if you want to bypass the shell. (By passing multiple args, which IO#popen does not allow)
Usage:
require "open4" stdin, stdout, stderr, pid = Open4.popen4('nroff -man') or include Open4 stdin, stdout, stderr, pid = popen4('nroff -man')
