I guess this is obvious advice, but then again we all need the obvious
stated from time to time: Since it seems to be tricky maybe a more
mechanical approach would help -- reproduce it with a script that just
uses module socket, then reproduce it with the equivalent C program if
necessary? Then if it's still not apparent, to keep zeroing in on what is
different between ab and your script, you can go in the other direction,
simplifying the ab code drastically, until your two programs are identical
apart from the one thing that makes the Python code slower (hopefully
you'll spot the problem before that happens ;-).
