I would really have wished people had picked it up back in january and
helped catch some of the bugs there, so we won't have to wait for 3.4
before it becomes really usable :o)

If people could try and give v3.4-rc2 with this patch applied a run,
it would be really helpful: http://patchwork.ozlabs.org/patch/151700/
So far it seems stable to me, but my setup most likely won't catch
every problem.
