Sounds good to me. In 3.0 we should probably not have os.popen*(), nor the popen2 module at all, and do everything via the subprocess module. I wonder if we should even get rid of os.system(); then there should be a subprocess.system() instead. And do we even need os.fork(), os.exec*(), os.spawn*()?
