Closing UDPListener makes Unity3D freeze

[youegraillot]

I'm using SharpOSC with Unity and when I close the UDPListener Unity freezes.

I fixed the problem by setting a timeout to ClosingEvent.WaitOne(timeout).
I don't know if it's good code but it seems to work now.

public void Close()
        {
            lock (callbackLock)
            {
                ClosingEvent.Reset();
                closing = true;
                receivingUdpClient.Close();
            }

            ClosingEvent.WaitOne(1000);
        }

For me this didn't work.
I have this problem only on a windows laptop. On OSX Unity does not freeze, and neither on my PC.
