Unless you want to force the tool to re-stat all dependencies after each
build and bail out, there is not much to do. I find that requirement
questionable. I also wonder what problem you are really trying to solve.
Optimistic building sounds like the wrong solution to a real problem --
incremental builds being way too slow.
