Well, so the problem happens with sendfile_max_chunk set lower
than proxy_buffer_size. While I don't think that
sendfile_max_chunk 8k is practical, it probably worth fixing.
I don't think that suggested patch is right
though - it will not prevent infinite stall of transfering a big
enough data chunk, as timer set by write filter will be removed.
