      The current approach we take with WX memory protection is to run with enabled Write by default and turning Execute as needed.
      I think we should also try flipping this around and try running with Execute by default and turning Write as needed.
      This would give us a better coverage and flush more codepaths to have greater confidence in our "whack the mole" approach.
