Does your Rack app actually set "X-Accel-Buffering: no" in a response
header?  Your config mentions it:

               # The Rack application may also set "X-Accel-Buffering (yes|no)"
               # in the response headers do disable/enable buffering on a
               # per-response basis.
               proxy_buffering off;
               proxy_pass_header X-Accel-Buffering;

I've mostly forgotten about Rails 3.1 streaming myself :x

I know current nginx versions only send HTTP/1.0 requests to the
backends, which means you need to force the response to stream
via "X-Accel-Buffering: no" since HTTP/1.0 doesn't have chunked
responses,

You should also try using "curl --http1.0" to better simulate nginx
behavior with HTTP/1.0 for testing.
