How do I re-queue a test that has been postponed on Drupal.org? I'm trying to run the tests on a patch on Drupal.org.  The relevant issue is here.  The status is marked as Test request sent but more than a week has passed and the test hasn't been run.

I tried changing the issue status from Needs review to Needs work and then back to Needs review but that didn't re-queue the test.  If the test has been run, whether it succeeded or failed, there is usually a Re-test link, but since the test is marked as "test request sent" then the link does not appear.

How can I re-queue such a test?
You can post an issue to the drupal.org testbots project issue queue and get someone to look into it.
