question about proxy_buffers

[merlin corey]

I'm not Igor so I cannot be totally sure, but my understanding of it
has always been 1- requests to the backend can use only one buffer and
the response gets buffered to disk.  As such, I generally start out
sites with log level info (might be too low) and try to tune down
requests getting buffered if at all possible.  I also try to stick
with magic numbers good for the architecture (so 8 and 16 based,
generally).
