You mean opening a local-loop socket instead of a anonymous socket, 
hogging at least another apache process and then possibly spawning 
another process if the python-script is implemented as real CGI - not 
fast_cgi or python - is the better solution? I doubt that. More wasteful 
in all aspects, with small to any gain at all.

Unix uses pipes as IPC all the time. I fail to see why that is "rubbish".
