Hi Kazu,

The most straightforward way I know of to do it is through a bounded
channel (http://hackage.haskell.org/package/bounded-tchan or
http://hackage.haskell.org/package/BoundedChan). You'd fork a thread
to enumerate the output end of the socket and feed it request body
chunks through the channel, then do the reverse to proxy the response.
