- Optimized access to FastCGI environment using HashTable instead of linear search
- Allowed PHP_FCGI_MAX_REQUESTS=0 to disable PHP die
- Allowed PHP_FCGI_CHILDREN=0 to disable PHP spawn workers
Due to licensing restrictions that actually don't allow anybody to use
the libfcgi code without prior approval from Open Market, which is
impossible to obtain - we decided to reimplement this interface from
scratch. The result is actually slightly faster, and more importantly,
clear of any copyright issues.
