OK Assumption bussting time

Intel is not hiding it, note all the publicity earlier on in the year. Unfortunately the bug is in code that is so fundamental to how modern day multi threaded processors work that to fully fix it will require a fundamental redesign of the chips. Current chips[1] IIRC can't be patched without causing a slowdown.

The amount of slowdown depends on what each program is actually doing and can't be guessed.

AMD and other chip manufacturers have the same problem.

As to legal liability I doubt it, we wos warned.

[1] Please correct this if I'm wrong
