I really don't think you can have a common way to do this on both
systems. First, the way to kill a process is quite different on both
systems (the os.kill function works only on UNIX systems, and I don't
know is there is such a function available in Python for MS Windows).
Then, I really doubt the use of pipes will work on Windows ... In our
labs, there was some tries to port UNIX program using pipes under
Windows and bidirectionnal pipes did not work at all and were thus
abandonned.
But try googling for some package doing something similar. If you get
any answer, don't forget to warn the list :)
