We should have a separate test for that as Eric pointed out.

On the contrary, it may well improve the overall bot cycle time because
flaky tests are ran twice on new-run-webkit-tests if we actually have many
tests that are flaky because of this.

We also parallelize tests and resources are loaded from the disk (with
cache) so I highly suspect this will be an issue.
