<p>
This test makes sure that throwing an exception in the load callback will not stop further
dojo.io.bind() requests from proceeding. If <b>Error bind</b> is pressed, an exception
will be thrown in the load handler. <b>Safe bind</b> does not throw an error. In all cases,
the value of <b>testvar</b> should increase by 1 any time either button is pressed.
