Comment (by peterwilsoncc):

 The process WP takes to empty the trash is:

 * Loop through selected posts:
   - check if user has permission to delete post, die if not
   - check the type of post
   - delete the post
     - delete revisions (itself a loop)
     - delete comments (a loop)
     - delete post meta (a loop)
     - DELETE post
     - unschedule if a future post

 The action from this ticket becomes: optimise the processes of emptying
 the trash and deleting a post.

 Further discussion would be whether this is worth-while, as is often the
 case the questions and thought experiments to run are:
 * what are the pros and cons of doing so
 * what are the pros and cons of not doing so
 * what is the worst that can happen by doing this
