One possibility may be to have OMPI honour a config
file in /etc by default as well as the ones in $prefix,
so if a user built their own copy then they would have
to hack the code in order to disable the check.

I also really liked the idea of OMPI outputing a
message if a user tried to override a locked param,
much better to explain why something is bad rather
than just saying "no" (especially if you can say
"no, but you could try...").
