There are three parts to it:

  - some patches to GHC to generate the log files.  The patches are
    not yet in, but I hope to get them in in the next couple of weeks.

  - a Haskell library for parsing the log files.  This will be up
    on Hackage soon.  You can use this to write your own analysis
    tools, visualisers, or whatever.

  - The ThreadScope viewer itself, which will also be up on Hackage
    as soon as its ready.

So we fully intend to get this out there ASAP, although until GHC 6.12 is 
released you will need to use a GHC snapshot to generate the log files.
