title: Is it possible that repeated OnConnected will call before previous OnDisconnected?
body: <p>Imagine some spherical horse in a vacuum:
  I lost control of my client application, maybe some error has happened. And I tried to re-enter to the hub immediately.
  Is it possible, that OnConnected starts faster then OnDisconnected and I turn up twice on the server?</p>
  
  <p><strong>Edited:</strong></p>
  
  <p>Sorry, I didn't say than I meant SignalR library. I think if my application won't call stop() the server will wait about 30 seconds by default. And I can connect to the server again before OnDisconnected is called. Isn't it?</p>
