Multi-threading with .Net HttpListener

For completeness, here is what it would look like if you manage your own worker threads:

class HttpServer : IDisposable
{
    private readonly HttpListener _listener;
    private readonly Thread _listenerThread;
    private readonly Thread[] _workers;
    private readonly ManualResetEvent _stop, _ready;
    private Queue<HttpListenerContext> _queue;

    public HttpServer(int maxThreads)
    {
        _workers = new Thread[maxThreads];
        _queue = new Queue<HttpListenerContext>();
        _stop = new ManualResetEvent(false);
        _ready = new ManualResetEvent(false);
        _listener = new HttpListener();
        _listenerThread = new Thread(HandleRequests);
    }

    public void Start(int port)
    {
        _listener.Prefixes.Add(String.Format(@"http://+:{0}/", port));
        _listener.Start();
        _listenerThread.Start();

        for (int i = 0; i < _workers.Length; i++)
        {
            _workers[i] = new Thread(Worker);
            _workers[i].Start();
        }
    }

    public void Dispose()
    { Stop(); }

    public void Stop()
    {
        _stop.Set();
        _listenerThread.Join();
        foreach (Thread worker in _workers)
            worker.Join();
        _listener.Stop();
    }

    private void HandleRequests()
    {
        while (_listener.IsListening)
        {
            var context = _listener.BeginGetContext(ContextReady, null);

            if (0 == WaitHandle.WaitAny(new[] { _stop, context.AsyncWaitHandle }))
                return;
        }
    }

    private void ContextReady(IAsyncResult ar)
    {
        try
        {
            lock (_queue)
            {
                _queue.Enqueue(_listener.EndGetContext(ar));
                _ready.Set();
            }
        }
        catch { return; }
    }

    private void Worker()
    {
        WaitHandle[] wait = new[] { _ready, _stop };
        while (0 == WaitHandle.WaitAny(wait))
        {
            HttpListenerContext context;
            lock (_queue)
            {
                if (_queue.Count > 0)
                    context = _queue.Dequeue();
                else
                {
                    _ready.Reset();
                    continue;
                }
            }

            try { ProcessRequest(context); }
            catch (Exception e) { Console.Error.WriteLine(e); }
        }
    }

    public event Action<HttpListenerContext> ProcessRequest;
}
