    Add security enhancements suggested by Jesse Ruderman.
    
    We were going to put these in the security slider, but perhaps they should be
    set by default. There will be a perf impact, but let's see if anyone notices
    and complains, at least for a beta or two. If not, maybe we can even set these
    in a release.
