I've got it about half done at this point. What's still to be done is
build the PostgreSQL example and the specialized post-processing code.
But the basics -- how to build "blktrace" from source and run it -- are
there. It will probably be next weekend before I get a chance to build
the PostgreSQL example.

If anyone wants to comment on it, the best way might be to join Github
and send me in-project messages there. I've got some documentation
questions I need to ask on the blktrace mailing list.

I've never met a happy clam. In fact, most of them were pretty steamed.
