Are we seriously having a discussion in which the merits of favouring pre-commit code review for the things like TCP stack are in doubt? I'm not saying we need to seek universal consensus on all changes, rather, that I would strongly prefer that people committing to this code seek review (and clearly indicate it in commit messages) before rather than after sticking things in the tree. This stuff is incredibly subtle, and debugging problems in the field is vastly harder than catching them early in the cycle. I certainly wouldn't commit any non-trivial change to the code in question without asking someone to go through it line-by-line, and I'd prefer if others took the same view, as I often end up chasing the bugs later, in the field, where it is hardest to do so.
