NBD can become contended on its single connection. We have to serialize all

Idea is that it can now use multiple CPUs concurrently...?
Do you have a diff for the nbd-server, too?
Pavel
nbd-server doesn't need anything special, it just works. I have a patch for
nbd-client so you can open multiple connections to setup the NBD device. You
can find my patches for the userspace stuff here
