Create epoll object,
open many client TCP sockets,
adjust their send buffers to be a bit more than request header,
send a request header — it should be immediate, just placing into a buffer, register socket in epoll object,
do .poll on epoll obect,
read first 3 bytes from each socket from .poll,
write them to sys.stdout followed by \n (don't flush), close the client socket.

Limit number of sockets opened simultaneously — handle errors when sockets are created. Create a new socket only if another is closed.
Adjust OS limits.
Try forking into a few (not many) processes: this may help to use CPU a bit more effectively.
