For 99% of my usage (I suspect for most other peoples' as well, at least on
Unix-y systems), this is all I need:

    for line in os.popen("some pipeline"):

No cheat sheet necessary.  I don't see how subprocess could have made that
common idiom any simpler.  Maybe it's better at doing esoteric stuff,
however that falls into the 1% where a simple os.popen isn't adequate.
