I think you're OK, it's just you don't have job control (and all the
paraphernalia of controlling terminals, sessions, and the stuff zsh-workers
will know I don't really understand).
In this case, the NOHUP option is irrelevant --- because you don't have
job control (it's determined by the MONITOR option which is unset in
non-interactive shells), the shell doesn't send SIGHUP to processes on
exiting (without job control it doesn't have much idea of which
processes would need it). So I think you get the effect you want.
