Fastcgi chunked data

[Ensiferous]

That's a lot of debugging when you could just have read the wiki
instead: http://wiki.nginx.org/HttpFcgiModule#fastcgi_buffers

"If you want to disable buffering to disk for all replies that are
greater than the FastCGI buffers and transfer data synchronously to the
client set fastcgi_max_temp_file_size to 0."
