// Tests for the UdpSocketWrapper interface.
// This will test the UdpSocket implementations on various platforms.
// Note that this test is using a real SocketManager, which starts up
// an extra worker thread, making the testing more complex than it
// should be.
// This is because on Posix, the CloseBlocking function waits for the
// ReadyForDeletion function to be called, which has to be called after
// CloseBlocking, and thus has to be called from another thread.
// The manager is the one actually doing the deleting.
// This is done differently in the Winsock2 code, but that code
// will also hang if the destructor is called directly.
