I decided to go another way as I really unsure about using all this staff
in a context of the thread in nbd server. And it'll be 1-2 patches.
Possibly, they'll be ready on March 9.

On the other hand, the most interest part is nbd-reconnect series and it
doesn't seem feasible to finish it for 4.0. (it's possible that March 9
would be the only my working day from 7-11)

So, I think, let's move this all to 4.1.
