I think you're going to make me eat my words (http://www.open-mpi.org/community/lists/devel/2013/02/12143.php). I just recently lost my access to InfiniBand test gear, so I can't test this myself. Hypothetically, it should be fine. But throwing in an untested change literally right before a release without IB vendor say-so really, really gives me pause... Mellanox?
