Was pleasantly surprised by the comments. But while the codebase is grokkable (every line is simple), it's brittle [1]. Not saying it's a big deal: brittle codebases are fine when the codebase is only going to be touched by a small amount of people. Less so when the code is going to be used and modified for decades by thousands of people (in OS, compilers, browsers...). [1] Unchecked assumptions everywhere, #ifdef with platform specific code everywhere, singletons everywhere. Only spent 5 minutes browsing the code, I'm sure there's more examples.
