This seems like an excellent way to write shell scripts in Python. I never consciously realized it before, but I've always wanted something like this. I have a strong distaste for Python's subprocess library; for example Popen.wait() is liable to deadlock under certain conditions http://docs.python.org/library/subprocess.html . It's not immediately clear to me from the source code if this module avoids that pitfall.
This also parallels closely with my experiences. One of my high schools had a student body of 400, where everyone tended to be friends with everyone. On the other end of the spectrum, my college was the "most diverse school in the United States" and the largest school in Virginia (George Mason University); everyone pretty much stuck to their group that most represented themselves.
What are the chances this DoS relates to the recent algorithmic-complexity vulnerabilities?
Another great way to shoot yourself in the foot (and getting it way way wrong) is to block all Googlebot IPs except for one.
