In essence, you're describing FastCGI. A Python program (or, indeed, any
program) which uses FastCGI runs continuously and waits for the incoming
request on a TCP socket (instead of as a sys.stdin stream + env vars
immediately after process startup).

The key description is here:

  http://www.fastcgi.com/drupal/node/6?q=node/15

(The sections have no anchors; you're looking for the section titled "2.
FastCGI Interface")
