Project idea: disk-activity visualization

[Poul-Henning Kamp]

If somebody here is looking for a project I would like to add something
like this to GEOM:

	http://www.itworld.com/Comp/3380/UIR990101perf/

It would be a flag you set on the consumer(s) or provider(s) you
were interested in monitoring, and then a number of pages of RAM
would be mapped from kernel to userland with an array of counters
which increment on access.

The kernel bit is rather trivial, the tough part is presenting and
visualizing this in a sane way.

Any takers ?
