We've got an NBD server ("flexnbd") that does
thread-per-client-connection in a fairly nasty way. I can't say I can
recommend it particularly, but that might just be because we didn't do
it very well.  Our use case generally only has a single client connected
to each server process at any one time anyhow, so it's all a bit
gratuitous.

I've got half a golang NBD server hanging around *somewhere*, I think I
got as far as implementing the newstyle negotiation.  Happy to dig that
out if it's likely to be of interest to anyone. "Write an NBD server in
it" has become my get-to-know-a-language project :D.
