Great data Vijay, thanks! Benchmarks are always nice to have.

Certainly could work, but we'd need far better tooling.
Too, most compilations are sure to be in debug mode, and already 
fast. Release compilations are relatively rare-er and if it takes 
longer, no big deal? I guess I'm not working on projects big 
enough that it matters -- our release builds still complete in 
under 60 sec.
