I agree that it shouldn't deadlock (worst case swapping to a file on zfs
should be disallowed), but is there a particular reason you created a
file on ZFS rather than creating a zvol to swap to?

ISTM that creating a volume would result in better performance than a
file and I can't see any downside to it.
