We could, but that would be runtime, and it would slow down every ioctl
call, but perhaps not enough to matter.

The real work is changing each program, and we already know a bunch of
those: racoon (in-tree), nmap, samba.  When those are fixed and we don't
know of any more, then it would make sense to worry about finding uses
we don't know about.
