* [@drew](https://twitter.com/drewbervisor) - pointing out AC bit in RFLAGS can be set in usermode. I originally assumed since the `STAC` instruction could not be executed in usermode that `POPFQ` would throw an exception if AC bit was high and CPL was greater then zero. Without this key information the project would have been a complete mess. Thank you!
