Comment (by pembo13):

 @desrosj this really isn't about overwriting variables. I'm not sure that
 it should be acceptable for WordPress AJAX to break just because a cookie
 exists with the name "action" even through WordPress itself isn't
 explicitly looking for a cookie.

 Checking $_GET or $_POST would avoid this. Also, it's a very difficult bug
 to track down once it's triggered.
