How about just ignoring the problem for the /proc interface? Non of the
suggested solutions would work well for simple shell-scripts anyway.

The suggested sysctl_s interface could be expanded to allow more than
one variabel to be manipulated at the time; making it possible for "real
programs" to get a consistent view of the variables when they need.

This would allow for the one-value-in-file approach and totally
eliminate the need for parsing.
