When the commit queue rejects a patch due to test failure it says what test(s) failed, but it doesn't specify what platform the commit queue is running on. This makes the failure harder to understand.
This is a valid concern, since we have 3 instances of the queue. 2 are Snow Leopard, one is Leopard.
This will be fixed as part of the patch on bug 58348. *** This bug has been marked as a duplicate of bug 58348 ***
