Ingo, can you please stop blocking this? It's getting ridiculous.

We've been waiting over 8 months for this to go in.

While we've been waiting most of our users have learnt to use operf instead,
which doesn't require raw codes.

I would also add that exactly zero users have asked for a feature where perf
downloads and rebuilds itself. In fact many of them would consider that a
security breach.

cheers
