A sorta proper Duplex stream useful for piping into, duplicating and
destroying. The reason this exists is because there is some weird timing issue
in how back pressure is handled preventing bl from handling the case of
being piped into and then piped somewhere else. This is super apparent when
dealing with requests.
var http = require('http');
var buffr = require('buffr');
//
// While this is not very useful, this will actually work and we will store the
// request in the `buf` stream if we need to duplicate and repipe.
//
http.createServer(function (req, res) {
var buf = req.pipe(buffr())
buf.pipe(res);
}).listen(3000);
