Sure, give it a shot. Looks like subprocess.Popen was intended to
replace os.system in any case.
Except that output is not 'real time' with straight Popen, and doing so
reliably on every platform (cough - windows - cough) is not completely trivial. You also have to handle buffered output, etc... That code is very fragile, so this would be quite a lot of testing to change, and I am not sure it worths it.
It doesn't have to be "real time". Just use .communicate() and print out the stdout and stderr to their appropriate streams after the subprocess finishes.
