Or use some mechanism like verifiedexec(4), load those parameters from
a file, if it's a pain to squeeze new attributes into the fs structures.
By the way (I may out myself as a NetBSD newbie here) is there currently
a way to tweak a process's memory priority, analogous to giving it a
scheduling priority with setpriority(2), or was that part science fiction?
