There's a good chance that setting the path-completion style to false will help in this case. That does disable a useful feature - though it is only a useful feature if you know it is there and use it. If not even SIGKILL works, it is stuck in kernel code. That doesn't surprise me much with NFS. That's not easy to workaround in the zsh code - other than by disabling functionality as with my path-completion suggestion.
