Yup. I took over and somewhat froze.. I have some stuff partially done
(and that actually works) that changes the batching, moving it away from
per-cpu and improving the latency situation but I wasn't to happy with
some aspects of the resulting patches, and finally got pulled on various
other things, so this work took the dust.

I can try to dig my stuff out when I'm back from travelling, in a week
or so, if there is some interest. I was thinking about looking at it
again anyway.

Cheers,
Ben.
