They probably do not. Try to _heavily_ overload machine. (8Meg and
swap over nfs and build kernel and ping -f machine and tcpspray
machine). It will deadlock.

SWapping over NFS requires generic _swapping_over_network_ to work. I
have patches to swap over nbd, along with modifications to TCP layer,
so it should work. Unfortunately, it patches quite a few places in TCP
and I do not think it is good candidate to go into standard kernel.

This one should work.
