Why is there a significant performance improvement, considering that
mod_python embeds the Python interpreter in the web server, while SCGI
keeps the interpreter in a separate process?  It would seem that the
inter-process communication between Apache and the SCGI server would
add overhead and thus degrade performance.  Thanks.
