My impression was that we were practically there - but we ran up against a hang bug which *may* have had a root cause elsewhere than Cake itself.  I strongly suspect we're tickling a HW driver bug, but we need someone with a different flavour of 100Gbps NIC to try (and hopefully fail) to reproduce it.

There's not much hope of my getting that calibre of hardware myself.
