It's a nice idea, but it's probably one of those problem thats best
solved at least partially in userspace.

I _don't_ like the idea of using a special program to do the setting up though.
But if it can be 'programmed' with "cat /etc/xyzzy > /proc/interpreters"
then I'll be happier :-)
The trouble is that being able to use 'cat' would require considerably
more smarts (and state) in the kernel part of the code. This way, I
can require that all changes to the list must result from a *single*
write() call, making the /proc/interpreters device essentially
stateless, and the kernel needs to only do security-related checks.
