php-fastcgi and memory leaks

I'm confused - when using a command similar to the one below, is it 
spawn-fcgi handling memory or php-cgi? When I check the processlist (ps 
aux) I see 4 instances of "php-cgi", each one with a slowly growing 
memory usage.

Maybe its the app I'm using which doesn't finish correctly. Its 
contributed to by a few different developers, some of which are new to 
the system and might not be finishing their scripts with the correct 
return state.
