The subprocess module is also supposed to replace os.system and
os.spawn*, neither of which involve opening pipes. (I use it for that
functionality just as often, if not more so, as for piped subprocess
communication). All rationalizations aside, I think Popen is a poor
name for the class. But I would imagine the odds of it ever being
changed are miniscule (Python 4?).
