Just stop arguing.

The 'cycles' thing is documented. It's CP:U cycles. This is just a *fact*.

I have now blocked you. You will get no more replies from me, because
it's not worth my time.

I simply have better things to do that deal with people who cannot
accept documented and existing behavior, and spend days arguing that
their broken fix was a "fix".

Just go play in any of the other open source projects that (sadly)
don't have regression rules.
