Description:
------------
each FPM process have the same name (the command line used to launched it).

It would be great to name them according to their type.

The master process: "php-fpm: master process (path/to/conf/file)"
The children processes: "php-fpm: pool www.foo.bar"

Test script:
---------------
#!/bin/sh

ps a | grep fpm

Expected result:
----------------
21744 pts/3    S+     0:00 php-fpm: master process (/usr/local/php-trunk/etc/php-
fpm.conf)
21745 pts/3    S+     0:00 php-fpm: pool www_chroot
21746 pts/3    S+     0:00 php-fpm: pool www_direct

Actual result:
--------------
23464 pts/3    S+     0:00 ./sapi/fpm/php-fpm
23465 pts/3    S+     0:00 ./sapi/fpm/php-fpm
23466 pts/3    S+     0:00 ./sapi/fpm/php-fpm
