I have no objections to the text, but I do wonder about the placement.
The "adding syscalls" document isn't about *invoking* them; I suspect that
few people will see it there. The coding-style document isn't quite right
either, but I wonder if it might not be a better place in the short term?

What we may really need is an "assorted rules" document that sits near
coding style; we can put stuff like this text, "volatile considered
harmful", and so on there.
