Well it is spinning in rendezvous_request due to this loop:

again:
    len = sizeof addr;
    sock = accept(xprt->xp_fd, (struct sockaddr *)(void *)&addr, &len);
    if (sock < 0) {
        if (errno == EINTR)
            goto again;
        return (FALSE);
    }
There was the same loop in the old glibc code as well
so nothing there has changed there...

It definitly has something to do with creating the
TCP listening socket since the UDP socket seems to
be fine:

# rpcinfo -T udp localhost 100011
program 100011 version 1 ready and waiting
program 100011 version 2 ready and waiting
# rpcinfo -T tcp localhost 100011
rpcinfo: RPC: Remote system error - Connection refused
