Attempt at a reduced test case for EvanOxfeld/node-unzip#20

highWater.js

var test = require('tap').test;
var PassThrough = require('stream').PassThrough;
var path = require('path')
var fs = require('fs');
var zlib = require('zlib');
var PullStream = require('pullstream');

    .pipe(fs.createWriteStream(path.join(__dirname, 'test.in')))

  deflater.write(loremString);
  deflater.end();

  function runTest(ps, callback) {
    ps
      .pipe(288, zlib.createInflateRaw({
        chunkSize: 64,
        highWaterMark: 2

      .pipe(new PassThrough())
      .pipe(fs.createWriteStream(path.join(__dirname, 'test.out')))
      .on('close', function() {

        t.equal(file.toString(), loremString);

  }
});

Added pullstream to the test case. Unfortunately, still doesn't recreate EvanOxfeld/node-unzip#20
