On my OFED 1.4.1 RHEL4u6 systems, rdma_bind_addr() fails when attempting to bind to 127.0.0.1 per the email I sent Friday:

I have not checked any other combinations; Steve was saying that he saw it rdma_bind_addr() succeeding on his machines with OFED 1.5.1rcwhatever (I don't recall the OS he said he was using).
