[Haskell-cafe] Simple binary-protocol through network test

[Yves Parès]

Okay, so I turned off every buffering using hSetBuffering hdl NoBuffering on
both Client and Server, but I doesn't fix it...
BTW, I tried to do the same without your package, i.e. simply through Lazy
ByteString and Binary, but it doesn't work either, I come up against the
same issue.
