Need network troubleshooting help

Gordon, could you tell me where 'key' gets locked in https://github.com/espruino/Espruino/blob/master/libs/network/jswrap_net.c#L169-L172

          key = jsvAsArrayIndexAndUnLock(key); // make sure "0" gets made into 0
          jsvMakeIntoVariableName(key, val);
          jsvAddName(query, key);
          jsvUnLock2(key, val);
