CGI starts up a new process for every request, using stdin/stdout for 
passing information.  I believe WSGI can do that, but I believe it can 
also do in-process requests (think mod_python, only with a Python web 
server), external process requests (think FastCGI or LRWP), etc.

I could certainly be mistaken, it's been a while since I looked into any 
of it.
