Bytes, Strings, Encoding

Hello,

I am working on the subprocess.Popen module for Python 2.7 and am now moving
my changes over to Python 3.1 however I am having trouble with the whole
byte situation and I can't quite seem to understand how to go back and forth
between bytes and strings. I am also looking for the Python 3k equivalent
for the Python 2.X built-in buffer class.

One version of the file with my modifications can be found here  <
http://code.google.com/p/subprocdev/source/browse/subprocess.py?spec=svn5b570f8cbfcaae859091eb01b21b183aa5221af9&r=5b570f8cbfcaae859091eb01b21b183aa5221af9>.
Lines 1 - 15 are me attempting to get around certain changes between
Python 3.0 and Python 2.7. Further down on line 916, we have the function
"send" and "recv" in which I am having the most trouble with bytes and
strings.

Any help is appreciated. Feel free to comment on my blog
http://subdev.blogspot.com/ or reply to the last.

Thanks in advance,
Eric
