Yes, I've done another iteration but it needs testing. I'd prefer one of
the later versions finally. It seems that we're also seeing the
effect of the race condition on the signalling variable.
However, we can also go incremental: do a like-v2 fix first, then fix the
races in nvme and then add a more general fix for all rdma.
