Making sure serving.run_with_reloader works as it should. Making sure th...

Hi!

Probably there are better approaches to implement this but ...

When you try to use `@werkzeug.serving.run_with_reloader` with gevent-socketio like in the snippet bellow  it will become very unstable.

This is happening when using: gevent 1.0 RC2

```python
@werkzeug.serving.run_with_reloader
def serve_programmableio():
    shared_app = SharedDataMiddleware(app, { '/': os.path.join(os.path.dirname(__file__), 'static') })

    SocketIOServer(
        (app.config['SERVICE_IP'], app.config['SERVICE_PORT']), 
        DebuggedApplication(shared_app),
        resource         = app.config['SOCKET_IO_NAMESPACE'], 
        policy_server    = app.config['SOCKET_IO_POLICY_SERVER'],
        policy_listener  = ( app.config['SOCKET_IO_POLICY_LISTENER_HOST'], app.config['SOCKET_IO_POLICY_LISTENER_PORT'] )
    ).serve_forever()
``` 

What happens is that 2 gevent files are constantly modified `/gevent/_semaphore.so` and `/gevent/core.so` so you will get  something like this executed every second:

```shell
 * Restarting with reloader
 * Detected change in '/home/nevio/.python-eggs/gevent-1.0rc2-py2.7-linux-i686.egg-tmp/gevent/_semaphore.so', reloading
```

or

```shell
 * Restarting with reloader
 * Detected change in '/home/nevio/.python-eggs/gevent-1.0rc2-py2.7-linux-i686.egg-tmp/gevent/core.so', reloading
```

Hope this helps!
