Stream overwhelmed by `ResponseStream` causing memory leak

[buptsb]

https://github.com/flatiron/union/blob/master/lib/response-stream.js#L162

ResponseStream.prototype.write = function (data) {
  this.modified = true;

  if (this.writable) {
    this.emit('data', data);
  }
};

This function push data into destination streams, eg. HTTP response, without considering back pressure, it will blow the memory up when serving large static files.

This module shouldn't be used anymore but will see if your patch fixes and still passes tests
