As of now nginx will always buffer fastcgi response up to full buffer
(see fastcgi_buffers directive) filled.

If you really need data to be flushed immediately, you may try the
patch from here:

http://mailman.nginx.org/pipermail/nginx/2011-August/028324.html

It is to address completely different problem, but as a side
effect with the patch complete fastcgi records will be sent without
further buffering.
