nginx assumes all fastcgi params will fit into single fastcgi 
record (i.e. no more than 64k), and usually this assumption is 
correct.

Just use normal way of passing request_body and you'll be fine.  
This one isn't scalable anyway as it requires client_body_buffer 
to be set big enough to contain full request body.
