If this is defaulting to RDMA, we may need some stuff from @franzpoeschel for this to be stable. You might force it to use TCP rather than RDMA. (Don't let it find libfabric on the build would be one way to do that.)

That's good timing then, I've started working on cleaning my branch up yesterday to make it mergeable.
