  // Turns out, it's quite tricky to get right:

  // Using !!navigator.geolocation does two things we don't want. It:
  //   1. Leaks memory in IE9: github.com/Modernizr/Modernizr/issues/513
  //   2. Disables page caching in WebKit: webk.it/43956
  //
  // Meanwhile, in Firefox < 8, an about:config setting could expose
  // a false positive that would throw an exception: bugzil.la/688158
