I'm sat at the Haskell Hackathon, and dons is doing a demonstration of
a tool called vacuum which can observe the state of ghc's heap while a
program is running, in various states of evaluation. I'm getting
pretty excited that this could be used to generate a hat trace using
ghc-api, rather than hat-trans.
I wanted to check if anyone had looked at the API this is using or
not, and if anyone knows of any immediate trip-wires that I might
encounter thinking about this.
