Actually PHP-FPM is a FastCGI implementation, with the F standing for FastCGI: http://php-fpm.org/
suPHP is similar to suexec and often used with CGI but that doesn't change my point that mod_php is not used on shared hosting (or at least responsible shared hosting).
On Python and Ruby, I just meant the principle of having a persistent interpreter process running outside the web server, not FastCGI specifically.

Ah, sorry, I was actually thinking of suexec when I said suPHP. Either way, I'm not very much concerned with shared hosting.
I see a big difference between fastcgi and using an application server, possibly because I remember the pain of using fastcgi with Ruby, and the major differences when I set up an application server instead.
