As pointed out elsewhere, a fs-interface would still need documenting, as
it'd be a "new" interface.

The real win with using an fs interface is that the kernel is in charge of
turning mib names into locators. Thus we can be use that (for instance)
net.inet.tcp.cwm_burstsize will always address the right thing. With the
current interface, the text name is translaged to a numeric MIB number by
the sysctl program, and that number is fed to the kernel. If thus there
are synchronization problems between the two.

Take care,
