According to the apache website..
PHP child process management (PHP_FCGI_CHILDREN) should always be disabled
with mod_fcgid, which will only route one request at a time to application
processes it has spawned; thus, any child processes created by PHP will not
be used effectively. (Additionally, the PHP child processes may not be
terminated properly.) By default, and with the environment variable setting
PHP_FCGI_CHILDREN=0, PHP child process management is disabled.
Ref : http://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html
Is this something you would agree with?
My guess is that would mean APC wouldn't work similar to running php-cgi..

FPM does sound like the answer to everything with all the benefits and
addressing all the drawbacks.. At least thats what it says on the tin..
