The current isolate tests don't work in drt/dartium because the DOM isolate can't use Isolate.spawnFunction. To avoid this problem, this change makes the affected tests start out by doing an Isolate.spawnUri with their own main file, therevy running the test in a non-DOM isolate. The test results are propagated back to the original isolate. I haven't been able to test dartium yet. I might be missing Selenium.
