Make a system call that returns an array of 16 bit numbers?

I prefer having /proc as it is, but binary files in /proc join the
disadvantages of /proc (overhead) and kernel calls (the need for
special programs to access the information). So please either make
files human-readable or just get rid of them altogether.
