Kudos to [@marcan](https://social.treehouse.systems/@marcan) for finding a "chicken bit" in Apple's M2 and M1 chips that disables DMP, the optimization that leaks secret encryption keys. This is significant. A couple caveats, though:

-- This isn't officially supported, or even documented anywhere, by Apple. It appears to turn off the DMP but no one knows (yet) what else it might turn off.

-- This can only be done on Linux, at least for now. There's no known way for MacOS to support using these bits.
