[Pharo-project] UDP Listener example?

I'm trying to build a display for some instruments that multicast readings using UDP. I started out using CocoaAsyncSocket on Mac (https://github.com/robbiehanson/CocoaAsyncSocket) and I have to say it has a really wonderful api - would be worth cloning it. However, want to do the same thing in Pharo so I have typed this little snippet into the workspace: [| socket | socket := Socket newUDP. 10 timesRepeat: [| s | s := String new. socket receiveDataInto: s fromHost: (NetNameResolver addressFromString:'255.255.255.255' ) port: 4848. Transcript show: s.]] fork and it doesn't seem to do anything. What have I missed? Pharo 1.3 stable on SnowLeopard BTW. Thanks, -Todd Blanchard
