Their modifications are now fetched directly at the source, from the github account under their name, without redistributing a line of their code in a patchfile or otherwise. If CloudFlare ever wake up to notice that someone created else created that github account in their name and take it down and action against those who put it up, the fetch will simply stop working.

The repository really appears to be provided by CloudFlare themselves, given the sheer amount of other repos available through the account in question. That as least is the assumption I may make in good faith where I live, as well as that whoever created the account using addresses did so with sufficient benediction from his/her/their employer.

I've been spending some time re-using old code of mine to make afsctool multithread capable. This useful utility for transparent compression already gets a performance boost from the CloudFlare patches, and even more from parallel execution.

I was planning to wrap that up in a submission but will now do so only if there appears to be a certain demand.
