Are there any restrictions/standards for pseudo-files placed
into /kern?  In particular, I'd like to create a new file
(perhaps called "summary") that provides, in one file:

cpu ticks
load
mem used/free
swap used/free
interrupt counts
net in/out
disk in/out (or at least "transferred" -- I don't think we
	     currently break it down into in and out)

and maybe more.  Adding such a file would help decouple things
like systat, top, and xosview from doing as much kernel
munging (and also cut down on the number of syscalls required to
get these stats!).
