There is special case code in content for mus. We need to run content_unittests (and content_browsertests) with --mash to ensure we are getting coverage.
We had something like this working for a while (with --mus), but it was nuked when we got rid of --mus. I think the right thing to do is similar to what we do with views_mus_unittests. That is, have content_unittests launch test_ws in a separate process. See views_mus_test_suite for how it does this.
Once we get this working we'll want to run it on the bots, similar to how we run mash_browser_tests.
