Nothing works :/

This looks like a great library that has the basic things I need, however, I can't get it to work. Additionally all test cases are failing.

I've even tried running your example verbatim, the error message is always the same:

if (require.main === module) {
  var workerPool = new WorkerPool(
    8,                // number of workers
    process.execPath, // path to the node binary
    './worker.js',    // path to the worker script
    {
      // The initData object that is passed to each worker exactly once before
      // any messages get sent. Workers receive this object via their
      // onInitialize callback.
      initData: {someUsefulConstant: 42}
    }
  );

  workerPool.sendMessage({message: 'hai!'}).then(function(response) {
    console.log(response); // Prints the response object from the worker
  });

  workerPool.shutDown().then(function() {
    console.log('All worker processes have now been killed');
  });
}

    throw new TypeError('Incorrect value of args option');

As for test cases failing the error messages don't seem to offer much info. They all just say Error: pit() tests should return a promise. I'm assuming this is because instead of returning a promise it's crashing? I'd love to use this module but I'm not sure if my env is wrong or if theres a bug. Travis does show the build as passing though.

which node version do you use?

the README.md is not up-to-date - there's a pending pull request that's fixing it: https://github.com/jeffmo/node-worker-pool/pull/3... now would be nice that this pull request would be accepted ?
