Since we are not sure whether pre-tokenized headers are worth adding at all (the performance gains are minimal), Gabriel has started removing that code and the parser instrumentation code we had in the pph branch.
This will simplify branch maintenance wrt merges, but we are still not sure whether we will do anything with PTH. So, I have created a sub-branch (pth-icm) to hold that code for now. This patch adds documentation for it. Committed to wwwdocs. Diego.
