//OK, since this was a bitch to figure out, here is some documentation for what is going on, and why we encounter exceptions when receiving data
//Context: The way our multi-client-udp-middleware works: packets are sent from Client A from any available (random) port to the predefined port of Client B.
//Client B then looks at the packet's originating (random) port that A used to send the packet and adds Client A to the list of clients to broadcast outgoing packets to.
//When sending packets back from B to A, it will now use the (random) port as its destination.
//As a consequence, here in Unity we must send and receive data with the same UdpClient using the same port.
//However, on some windows machines sending data to a port where there is no listener results in an ICMP response WSAECONNRESET
//E.g. see here: https://stackoverflow.com/questions/7201862/an-existing-connection-was-forcibly-closed-by-the-remote-host
//(This situation can occur if Unity is started before e.g. ASAP is running; in that case there is nobody listening to our packets)
//This ICMP response then silently kind of half-closes our UdpClient connection....
//Weirdly enough we can still continue sending data, but when we try to call UdpClient.Receive() it throws an exception --- EVEN IF THERE IS DATA WAITING IN THE BUFFER AT THAT VERY MOMENT.
//Even weirdly-er, we can just ignore the exception and continue using the udpClient for sending and receiving...!
//The current workaround simply catches the exception and ignores it :)
//Unfortunately, the incoming packet that caused the exception is lost
