This latest version looks very good. Just a few minor minor
comments that I did not noticed before.

1) What is the behavior on platforms that do not support RDMA?
    For example, will jdk.net.Sockets::openRdmaSocketChannel
    throw UnsupportedOperationException? If so, then maybe make
    that clear in the API sketch in the description.

2) Links to external references seem to have been inadvertently
    dropped. Prefer markdown links, e.g.

     ... form [Wikipedia][wikirdma] ...
