EspruinoWiFi - UDP / Broadcast not stable

Last message for today Gordon.
I managed to capture a crash using the isolated code above with debug enabled.
I changed the UDP server code to send a UDP package each 100ms and not every 10 seconds.

The last message was truncated to. Not two chars.

I think you should be abe to reproduce it with my isolated code. Just change the linux server to 100ms and enable debug on the espruino side.
