read _and_ write from/to commandline program

[lamzak8642 at my-deja.com]

Hi,

Is it possible to read from _and_ write to a commandline program (Linux
+ Python)? Apparantly I can't do this with os.popen() because it is
unidirectional.

I'm looking for something like this pseudo code:

	proces = magic.function('myprogram', "wr")
	proces.write('do this')
	result = proces.read

Any options?
