Pico and ESP8266

There's a bug for this and I'll try and get a fix in soon. It shouldn't be too hard - although having said that the Unlink doesn't say which socket has closed, so it could still cause problems.

You could check if sockets are closing by doing something like:

http.get("http://www.espruino.com", function(res) {
  digitalWrite(LED1,1);
  res.on('data', function(data) {
    console.log(data);
  });
  res.on('close', function(data) {
    digitalWrite(LED1,0);
  });
});

As a stop-gap you could do something similar to make sure you don't fire off multiple requests at once I guess.
