Since you have some implementation done, have you done any benchmarks with that?

I was thinking about this stuff due to the [thread about compilation speed](https://groups.google.com/forum/#!topic/mozilla.dev.platform/-5Ktzq74KTc) currently going on over at dev-platform (tl;dr: the Rust crate depgraph is now the long pole for compiling mozilla-central).
