+// 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.
