Shouldn't we update the status file instead with PASS || FAIL on linux and add
the bug number there? Then it is accounted for as a flaky test that we want to
fix in the test script reporting. Changing the test like this will hide the fact
that the test is flaky. It is no longer testing what we want it to test.
