I don't think you correctly understand how mod_fastcgi works.  It sounds 
like you are trying to link you application to apache.  Your fastcgi 
application is not part of the mod_fastcgi process.  Instead the 
mod_fastcgi handler creates a process manager process.  The process 
manager shows up as another httpd process.  It takes care of running 
fastcgi applications, each as their own process.  Your cgi will listen 
for socket connections.

Here is what my process tree currently looks like:

      httpd-+-httpd-+-adredirect
            |       +-2*[news]
            +-179*[httpd]

adredirect and news are both fastcgi applications.  They run as children 
of the process manager.  There are curently two copies of news running 
and 179 standard web server processes.

Statically linking mod_fastcgi into the httpd process would not change 
the structure of this process tree.

I don't know why your application is failing when called from the 
process manager.  What does the apache error log say?

There's no point in acting all surprised about it. All the planning
charts and demolition orders have been on display in your local
planning department on Alpha Centauri for fifty of your Earth years,
so you've had plenty of time to lodge any formal complaint and it's
far too late to start making a fuss about it now.
