Just remember: /proc is part of the user API. It contains system calls that
are implemented with open/read/write/close rather than syscall directly. As
such, you may not alter functionality that will break userspace[*].
[*] OTOH restricting stuff for security purposes does have merit, so I'm not
totally against the idea.
