[Nix-dev] Adoption of C4

[stewart mackenzie]

The minimal idea is: maintainers dont do 'deep' code reviews. They
just glance over the patch and make sure it qualifies as a correct
patch, as defined by C4. After travis goes green they hit merge.

If a bug gets in, its not their fault. The community responds quickly
with a fixing patch.

Main points a maintainer is aware of: no public API breakages and it
compiles. (travis does wonders for point 2).

This rather counter intuitive approach means contributors become more
careful. It also means more eyeballs are watching and when shit hits
the fan its all hands on deck.
