 impact on the frontend.

 As Dion indicates above, with the heartbeat API there is some amount of
 effect on the front end while editing. The same is true for revisions,
 autosaves and probably a few more things.

 There may be a solution for this by changing how we salt the cache for
 `WP_Query` to reduce invalidation to a subset of queries. A problem for
 another ticket.

 Under no circumstances do I think the solution is to deliberately store
 out of date date in the cache. To do so would replace one bug with
 another.
