// Expected behaviour
//   Create two files, throwing no errors. Or at the very least, if an error is thrown, it should be 
//   catchable by one of the two methods shown above -- presumably the callback method.
//
// Actual behaviour
//   Two files are indeed created, but the following error is thrown, and is uncatchable:
//
//  buffer:60
//        return this.utf8Write(string, offset);
//                    ^
//  TypeError: Offset is out of bounds
//      at Buffer.write (buffer:60:19)
//      at fs:387:52
//      at node.js:255:9
