kerneld (kmod's late unlamented predecessor) used to use Unix sockets
to communicate from the kernel to the daemon.  It forced everybody to
link Unix sockets into the kernel but there are some people out there
who want to use it as a module.  Also the kernel code for communicating
with kerneld was "unpleasant", see ipc/msg.c in a 2.0 kernel.
