Martin's notes:

here are my notes from our little session with me learning iogrind

- make it easier to package, using the stock valgrind from the
  distro: merge it upstream as exp-iogrind or produce a patch

- unexpanding addresses is broken in the address space view

Things to document for the newbies (a Help menu item with a few
lines of basic hints, or a link to docs in a wiki... ?)

- fsview: files go from light to dark (or reverse?), selected one is
  green, purple means ???
