I've personally had nothing but problems with spawn-fcgi and stopped 
using it years ago. The -b switch for the php-cgi config tells PHP to 
bind to an address:port, so you don't really need spawn-fcgi as long as 
something can keep an eye on the process.

We use supervisord to spawn & manage both PHP & Python services which 
sit behind nginx. A supervisor config with something like the following 
should get you going:

[program:PHP]
command=/usr/bin/php-cgi -c /etc/php.ini -b 8888
autostart=true
environment=PHP_FCGI_MAX_REQUESTS=100,PHP_FCGI_CHILDREN=3

[program:MyPythonProgram]
directory=/path/to/my/py/app/dir
command=/usr/bin/python mywsgiapp.py

Then in your nginx config simply create a config file for each FCGI 
environment (php/python) and add any "backends" (for python, 
specifically) to your vhosts.

You can even use supervisord to start/manage your nginx instance. We 
have supervisord manage everything, and have monit keeping an eye on 
supervisord as an added bonus.

You can see more on supervisord at http://supervisord.org, however the 
site is going through a server move at the moment so they've only got 
the manual up at the moment.
