See:

In IE6, I get the following failures:

FAILED test: ../../dojo/tests/_base/loader/xdomain/xdomain.html::xdomain::undefined assertEqual() failed:
      		 expected
      		 		 true

      		 		 false

modified test to work with ie6; fixes #13409

[Rawld Gill]

Test case 18 and 19 in dojo/tests/_base/loader/xdomain/xdomain.html should cause the loader to throw and the test should catch in order to notice the throw. Although the code path is going through a throw statement, for some reason ie6 is not throwing, which causes the test to report a false failure.

Watched the code in the debugger on ie6 and it is operating correctly.
