2. Execute "make DEV=ashell" in the latest zephyrJS build
3. Execute "make dfu" to flash ashell to Arduino101 and Reset device
4. Use the following command to connect to the ashell from a terminal $ screen /dev/ttyACM0 115200
5. acm> load test.js and Enter

Annotated the following code, this issue will disappear.

expectStandardError("calling require with a long name", RangeError, function() {
    require('supercalifragilisticexpialidocious');
});

This is due to the dreaded 80 character line limit in ashell. It works on IDE because that uses ihex, which strips whitespace and makes sure each ihex line is less than 80 char. I'm working on a fix for this.

@grgustaf Just FYI I don't plan on this making it into 0.3. It will be a big ashell change and I'd hate to destabilize things.

This will be fixed by zoltan's ashell refactoring.
