In any case, a panic action should be written with the assumption that
an attacker can cause a crash at will - as without smbd bugs, there
would be no need for a panic action :-).  

As that attack/weakness could just as easily be in root-run part of
smbd, I think becoming root again would not cause any additional danger.
