And if you do this for every "unsafe" function in Octave, you will
break a lot of things.  For example, the help system and plotting with
gnuplot.

I think some other approach is needed.  I would recommend leaving
Octave alone and working on a restricted server environment (chroot
jail or similar) that would prevent a malicious user from doing any
damage to anything but his own sandbox.
