You seem to be missing the fact that ./py is run in a different process.
The "sys.stdout" that p.py uses is different from that in the program 
calling Popen.  In fact, it could be using a different Python.  The
situation is really similar to
     p = subprocess.Popen([<basic program>, 'aa'])
in that you have no way to "muck with the guts" of the subprocess, you
can only post-process its output.
