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*()?

I don't know about about os.fork; I surely like to have posix.fork. The posix module exposes many OS functions as-is. This has the advantage that their semantics are crystal-clear: they do whatever the system call does (which, ideally, is what POSIX specifies for it). So you can do systems programming in Python, and only need good knowledge of the underlying system calls (i.e. using Python as a better C).

For the subsystem module, the semantics is not so clear, in border cases.
